>Heat is the total energy of molecular motion in a substance.
>Heat energy depends on the speed of the particles, the number of particles (the size or mass), and the type of particles in an object.
>It is heat that will increase or decrease the temperature. If we add heat, the temperature will become higher. If we remove heat the temperature will become lower.
>Temperature is a measure of the average energy of molecular motion in a substance.
>Temperature does not depend on the size or type of object.
>Higher temperatures mean that the molecules are moving, vibrating and rotating with more energy and vice versa.
