| Heat is that form of energy which flows from a hot body to a cold body when they are kept in contact. | Temperature is a quantity which determines the direction of flow of heat on keeping the two bodies at different temperatures in contact. |
| The S.I. unit of heat is joule (J) | The S.I. unit of temperature is kelvin (K). |
| The amount of heat contained in a body depends on mass, temperature and substance of body. | The temperature of a body depends on the average kinetic energy of it's molecules due to their random motion. |
