MCQs, mostly true and false, taken from diffrenet sources
[/B]is there an intermediate between energy and matter
yes no i dont know Democritus was one of the first philosophers to say that everything was made up of particles too small to be seen.He believed these particles could not be destroyed or split. Democritus said that all changes in the world could be explained as changes in the way particles are packed together. true false memory metals can remember their shape. When brought to a certain temperature, these metals can be set to a shape that they never forget. They have many uses, including repairing broken bones. Even if the bones move, the metal always returns to its original shape, bringing the bones back to their correct position. true false Hardness is a measure of how easily a material can be scratched true false glass is an amorphous(has no crystalline structure) solid true false When mercury is dropped onto a surface, it rolls off in little balls. This is because the forces between the mercury particles are very strong, so the particles clump together. This force between particles of the same type is called adhesion.(it is cohesion) true false most viscous liquid is glass tar daambar honey most flammable liquid(N2O gas) true false what is most flammable oil(veg oil) true false Rock, sand, and seawater are all mixtures of the same substances – such as the minerals feldspar, mica, and quartz – but in different particle sizes. Rock contains these substances in chunks or veins; sand has them as small grains; and seawater contains them as tiny dissolved particles that are invisible to the eye. true false Granite is a common rock made of three differently coloured minerals called feldspar, mica, and quartz. The pink grains in granite are feldspar, the black grains are mica, and the light grey, glass-like grains are quartz. Granite is usually about 75% feldspar, 5% mica, and 20% quartz. true false fog is mixture of water and air called colloid, its particles are too small ever to settle out. particles are smaller than those in a suspension, but larger than those in a solution(eg sugar into liquid) true false Mud stirred in water is a type of mixture called a suspension; the particles are too small to see when mixed, but they eventually settle out. true false most soluble in water sugar (i think) salt Wood’s Metal is found in automatic fire sprinklers. It is an alloy (mixture of metals) containing bismuth, lead, tin, and cadmium.if the temperature gets too high, the metal alloy melts and releases the water. true false All the elements on Earth were formed in the heart of exploding stars. The early Universe was made of just two elements, hydrogen and helium, which formed into stars. At the fiery core of these stars, the hydrogen and helium were forced together to form new, heavier elements. Even heavier elements were created in the explosions of massive stars, called supernovas. true false There are 90 natural elements, ranging from the lightest, hydrogen, to the heaviest, uranium. true false Synthetic elements include plutonium and einsteinium. true false there is no proton in H atom true false Positively charged protons would normally repel each other, but the nucleus is held together by a powerful force called the weak nuclear force.(strong) true false In 1922, Bohr was awarded the Nobel Prize for Physics. true false in the periodic table elements are arranged in order of their ........ atomic mass atomic weight mass number atomic number One element that Mendeleyev left a gap for in his periodic table was gallium (element 31). Mendeleyev called it eka-aluminium because he predicted it would have similar properties to aluminium. (he predicted also germanium, and scandium.) true false An astronaut’s visor is gold-plated to reflect sunlight. it is corrosion resistant true false phosphorus compounds are used on the tips of matches. Phosphorus glows in the dark, an effect called phosphorescence. true false Argon is very unreactive and does not combine with other elements. In arc welding, metals are melted surrounded by argon gas. The argon keeps oxygen out, so that oxygen cannot react with the melted metals. true false Substances whose molecules contain different types of atom are called compounds. true false The element argon is a one-atom molecule. true false In this type of bonding, all the atoms lose electrons, which float around in a common pool. The electrons in this pool can move around freely, which is why metals can transfer heat or electricity so well. covalent bonds ionic bonds metalic bonds it is the enzymes in yeast that cause bread dough to rise. true false Cars fitted with a catalytic converter change the harmful gases into safer gases. When they enter the catalytic converter, the gases form temporary bonds with the surface of the catalyst. This brings them into close contact with each other and allows new, safer gases to form. true false ......is force of nature that kills most people in the world water(i think) fire air earth Smoke is compounds of hydrogen, carbon and oxygen. The rest of the material forms char, which is nearly pure carbon, and ash, which is all of the unburnable minerals in the wood (calcium, potassium, and so on). The char is what you buy when you buy charcoal. Charcoal is wood that has been heated to remove nearly all of the volatile gases and leave behind the carbon. That is why a charcoal fire burns with no smoke. true false Flame color varies depending on what you're burning and how hot it is. Color variation within in a flame is caused by uneven temperature. Typically, the hottest part of a flame -- the base -- glows blue, and the cooler parts at the top glow orange or yellow. true false On Earth, gravity determines how the flame burns. All the hot gases in the flame are much hotter (and less dense) than the surrounding air, so they move upward toward lower pressure. This is why fire typically spreads upward, and it's also why flames are always "pointed" at the top. If you were to light a fire in a microgravity environment, say onboard the space shuttle, it would form a sphere! true false Ash is something you get when you have burnt wood and the grey fine leftovers is called ash.Soot is something that if a train in the olden days passed through a tunnel and used coal as fuel would be left stuck on walls etc , very sticky and messy. Also find soot in Chimneys . Soot is a general term that refers to the black, impure carbon particles resulting from the incomplete combustion of a hydrocarbon. Ash is different than soot because ash is volcanic waste that volcanoes spew out when they erupt. Soot is your regular dirt that gets on you on a muddy day or dust from your attic. Note : data takenfrom internet true false Limestone is an important base that is dug from the earth in quarries. true false Ag, Au, Ca, Na are metals true false poor metals are tin and aluminium potassium and sodium(alkali metals) copper, silver, and gold(transition metals) ............is used in gold extraction cyanide(poison) crushing The transmission lines (electric cables) that bring electricity to our homes, schools, and offices all rely on ...... iron copper zinc brass Oleum is concentrated sulphuric acid. It is transported to manufacturing plants in tankers. Here, water is added to the oleum in precise measures to make the correct concentration of sulphuric acid. Sulphuric acid is used in the manufacture of detergents, paints, medicines, plastics, and synthetic fabrics. true false Bromine is the only liquid non-metal element. also used in photography true false there are....... noble unreactive gases(,argon, neon, helium, krypton, radon, and xenon) 6 5 7 8 Argon is used in light bulbs, xenon is used in lighthouse arc lamps, and helium is used to fill airships and hot-air balloons. true false The space shuttle uses liquid hydrogen fuel because hydrogen gives out a lot of power for very little weight. Hydrogen, like all fuel, needs oxygen to burn, so the shuttle has a tank of liquid hydrogen and a tank of liquid oxygen. A fine mist of the two liquids is sprayed into the engines and ignited (set alight). The hydrogen explodes, sending steam out of the nozzles and helping to thrust the shuttle into space. true false Margarine is made by passing bubbles of hydrogen gas through hot vegetable oil. true false When nitrogen gas is cooled to -196ºC (-320ºF), it turns to a liquid. Liquid nitrogen is so cold that it can freeze a substance in seconds. In hospitals, it is used to preserve blood and body parts for transplant. semen can be stored true false The stable structure of fullerenes(carbon allotrope:herecarbon atoms link together to form a ball-shaped cage ) works well on large-scale buildings.(eg geodesic dome) true false relationship between matter and energy is explained by chemistry physics astrology astronomy carbon compound called an ester gives an apple its distinctive smell. true false Racing bikes are often made from carbon fibre. This material is fireproof and five times lighter than steel, yet twice as strong. true false plastic bags are made from polythene polyethylene Polystyrene glass is a thick liquid that never completely sets (hardens). That is why old window panes are thicker at the bottom than at the top. true false Sand, broken glass, soda, and limestone are heated in a furnace. At around 1,500°C (2,732°F), the mixture melts to form molten (liquid) glass, which is cut into individual globules of glass called gobs. true false Heat-proof oven doors are made by adding chemicals to molten glass so that the glass lets light but not heat through. Car windscreens are made shatterproof by cooling molten glass rapidly with jets of air. Test tubes and other glass apparatus used in science labs need to withstand the heat of a Bunsen flame. This kind of glass is made heat-proof by adding boron oxide to the raw materials to make borosilicate. true false Ceramics are made by firing (heating) clay (fine particles of earth) in an oven called a kiln or furnace. true false Ceramics can be thrown (made) by shaping a lump of wet clay on a wheel (a turning plate). The potter places the clay on the centre of the wheel, then skilfully raises it into shape by hand. true false The pot is fired in a kiln. The first firing, called the bisque firing, hardens the clay. A coating called a glaze is painted onto the pot, and the pot is fired again. Glaze waterproofs the pot. true false Bio-ceramics now replace teeth and bones. true false NATURAL COMPOSITE: Bone is a composite of hydroxyapatite and a protein called collagen. The hydroxyapatite is a brittle but hard and rigid material that gives bone its structural strength. The collagen is soft and spongy, giving bone its flexibility. Bone is 80–90 per cent hydroxyapatite and 10–20 per cent collagen protein. true false Before recycling, paper is sorted into different grades. It is then mashed with water and chemicals to form a pulp. The pulp is cleaned (to remove staples, glue, or ink) and sprayed onto flat screens. When dry, the paper is used to make new products, such as newspapers. true false On Earth, the force of gravity on 1 kg (2.2 lb) is 9.8 newtons. true false Einstein realized that the speed of light is always the same. He then calculated that an object travelling near this speed acts strangely: it shrinks in length, increases in mass, and time slows down. He also calculated that mass alters space. So small objects do not travel in straight lines near a large object – instead they follow the distortions in space made by it. true false Heavy construction machines have large tyres for two reasons. The compressed air in the tyre helps to absorb bumps, so the ride is much smoother than it would be with a solid wheel. Large tyres also help to spread the weight of the machine over a much bigger area. This reduces the pressure on the ground and stops the machine sinking into the mud. true false The higher we go, the less air there is in the atmosphere above us. The deeper in the sea we go, the more water there is pressing down on us. true false 120 m (400 ft) DEEP: Divers cannot go any deeper than this without special suits to protect them from the pressure of the water. true false potential energy that powers bows and catapults is........PE gravitational(avalanche converts PE into KE) elastic A moving hammer has a lot of kinetic energy. As it strikes the nail, it slows down and loses its kinetic energy. The energy does not disappear, however. Some of it goes to split the wood to make way for the nail, some passes into the wood as heat energy, and some is converted into sound. true false When iron is heated in a furnace, it glows red-hot and then melts at a temperature of 1,535°C (2,795°F). At this temperature, its particles move about with lots of kinetic energy. At higher temperatures they move even faster, and the iron in the furnace starts bubbling. true false When an object such as a boat or an airship rests in a fluid (a liquid or gas), it has to displace (push aside) some of the fluid to make room for itself. The object’s weight pulls it downwards. But the pressure of the fluid all around the object tries to push it upwards with a force called upthrust. The object SINKS if the upthrust is less than its weight, but floats if the upthrust is equal to, or more than its weight. true false Not everything will float. A block of wood will float on water, but a lump of iron exactly the same size will sink. This is because a piece of wood of a certain size weighs less than the same volume of water, so wood floats on water. However, iron is much heavier than either wood or water. A block of iron weighs more than the same volume of water. This is why iron sinks in water. true false sound waves (The medium moves back and forth as waves carry energy through it, but it does not actually travel along with the wave.) true false Ocean waves are transverse waves that carry huge amounts of energy across the surface of the sea as they move up and down. A wave 3 m (10ft) high carries enough energy to power around 1,000 lightbulbs in every 1 m (3 ft) of its length. true false Radios, televisions, mobile phones, and radar use signals made up of electromagnetic waves. These are waves that carry energy as electricity and magnetism at the speed of light. true false UV rays can not cross glass true false Although we cannot see infrared, we can feel it as heat. When heat energy is transferred by radiation, it is carried by waves of infrared. true false Radio waves are the longest in the spectrum. They carry radio and TV signals around Earth. Radio waves from outer space are picked up by radio telescopes and used in studies of the universe. true false |
