Plz answer following questions
 
plz answer following questions
the best thermometer for measuring temperature of boiling water is........?
eating habit of squirrel........(herbi,carni,omni,?)
boiling of egg is which type of change?
why compass needle points to north?

hey
 
Best thermometr for boiling water is a thermometer with some organic liquid which have a boiling point more than 100 deg Celsius, alcohal is not applicable bcos it has a boiling point of 78 deg Celsius,which may burst.

Squirell is omnivore which means that it eats herbs,fruits,insects etc


A compass points north because Earth is a magnet.
The compass needle aligns with the magnetic field that Earth produces.
The geographical poles (true north) is the point where Earth's axis of rotation meets the Earth's surface.

Heating an egg usually denature its proteins which harden.

Infrared Thermometer is the best thermometer. Non Contact Measuring Temperature with Laser Point Sighting, Max. 968°F (520°C).

Squirrels are predominantly herbivorous not omnivores, subsisting on seeds and nuts, but many will eat insects, and even small vertebrates.

Boiling of an egg would be a chemical change. To understand why, you need to know the difference between a physical and chemical change. A physical change is a change that can be reversed, like water can turn into ice, but you can turn the ice back into water. A chemical change is a change that can't be reversed, you can't reverse a boiled egg into unboiled.

Herbivore eat herbs.
Carnivores eat meat or flesh.
Omnivores eat herbs,flesh etc.
If squirrel eat herbs,insects and small vertebrates even then it is has omnivorus mood of nutrition.











Growth is the only evidence of life.

Brother,I think sqirrel is an Omnivoruos animal.for it feeds/can feed on seeds and nuts,as well as insects,While Herbivores feed [B]exclusively on plants[/B].

[SIZE=3][FONT=Arial Black]1.boiling of[/FONT][/SIZE][SIZE=4] egg is chemical change as egg can`t be regained in to yolk.as old bonds are broken and new bonds are formed.example coal when heated then ash can`t be converted back.[/SIZE]


[SIZE=4] 2.squirrel is herbivore because it eats producers and herbivores eat producers.[/SIZE]

[SIZE=4]3.compass needle rest because earth is a huge magnet lies in space north south vise so every navigation instrument and magnet will rest north south vise [/SIZE]

oh..but her excellency also eats insects and some invertebrates.

Sis i'm still hazy,as enerally speaking,it's predominantly herbivore,but if you classify them on their mode of nutrition,I think they fall into omnivores.
