Heat Energy

Heat is a form of energy called thermal energy. It is the energy that is transformed from a hot object to a cooler object as a result of their difference in temperature. Sources of heat are electricity, candle, sun, burning and so on.

Temperature is a degree of hotness or coldness of an object. Temperature can be measured with the aid of a Thermometer, its unit is Celsius Kelvin.

Kinetic Theory Explanation Of Temperature

Since the molecules of a substance are in constant motion,they posses kinetic energy. Addition of heat to a substance causes an increase in the average kinetic energy of the molecules of the substance and thus an increase in its temperature .

Removal of heat from the body leads to a decrease in the motion of the molecules and hence reduction in their average kinetic energy, this result in a increase in temperature.
