Heat and Temperature

Heat :

1. Heat is the total kinetic energy possessed by all the molecules of a substance.

2. Heat energy depends on the speed of the particles, the number of particles, size and type of particles.

3. Heat is the cause, temperature is the effect. By adding or removing heat from a substance, its temperature can be increased or decreased.
For e.g. As we add heat to a substance its temperature increases and if we remove heat from a substance its temperature decreases.

4. Heat is a form of energy.

5. SI unit of heat is joule.

Temperature :

1. Temperature is the measurement of average kinetic energy of all the malecules of a substance.

2. Temperature of the substance does not depend on the size or type of particles of the object.

3. Temperature is the effect however with addition or remove of heat from substance, temperature of the substance changes. But heat will always flow from a  body at higher temperature to a body at lower temperature.

4. Temperature is not energy but a measure of it.

5. SI unit of temperature is Kelvin (K).
