1. |
The total kinetic energy produced by the vibration of all the molecules in a substance is called its heat content. |
The average kinetic energy of all the molecules present in that substance is called its temperature. |
2. |
It is a form of energy that gives the sensation of warmth. |
It is the degree of hotness or coldness of a body. |
3. |
Heat is the cause for the change in temperature. |
Temperature is the effect of heat. |
4. |
It is measured with the help of calorimeter. |
It is measured with the help of thermometer. |
5. |
Heat energy as such will not determine the direction of heat flow. |
Temperature is the indication for the direction of flow of heat. Heat always flows from the region of high temperature to the region of low temperature. |
6. |
Heat depends on the mass of the body. |
Temperature doesn’t depend on the mass of the body. |
