| S.N. | Heat | Temperature |
| 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. |
| 7. | Its SI unit is Joule (J). | Its SI unit is Kelvin (K). |
