Solution
| Heat | Temperature | |
| 1. |
Heat is energy in transit. When two bodies at different temperatures are brought in contact, they exchange heat. OR Heat is the form of energy transferred between two (or more) systems or a system and its surroundings by virtue of their temperature difference. |
Temperature is a physical quantity that defines the thermodynamic state of a system. OR Heat transfer takes place between the body and the surrounding medium until the body and the surrounding medium are at the same temperature. |
| 2. | Heat exchange can be measured with the help of a calorimeter. | Temperature is measured with the help of a thermometer |
| 3. | Heat (being a form of energy) is a derived quantity. | Temperature is a fundamental quantity. |
| 4. | S.I. unit: J (joule) | S.I. unit: K (kelvin) |
| 5. | Dimension: [L2M1T–2 K0] | Dimension: [L0M0T0K1] |
