| Heat is a form of energy obtained due to random motion of molecules in a system. |
Temperature is a quality which tells the thermal state of a body (i.e., the degree of hotness or coolness of the body) and determines the direction of flow of heat on keeping the two bodies at different temperatures in contact. |
| S.I. unit of heat is Joule (J) |
S.I. unit of temperature is Kelvin (K) |
| The amount of heat contained in a body depends on mass, temperature, material of the body |
The temperature of a body depends on the average kinetic energy of it’s molecules due to their random motion. |
| Heat is measured by the principle of calorimetry. |
Temperature is measured by a thermometer. |
| Two bodies having same quantity of heat may differ in their temperature. |
Two bodies at same temperature may differ in the quantities of heat contained in them. |
| When two bodies are placed in contact, the total amount of heat is equal to the sum of heat of the individual bodies. |
When two bodies at different temperatures are placed in contact, the resultant temperature is a temperature in between the two temperatures . |
