OVERVIEW OF HEAT VS TEMPERATURE
We can’t talk about heat without mentioning temperature.
Heat and temperature are two closely related terms but a clear distinction exists between the two of them.
The first major difference lies in their definition.
Heat is a form of energy that is transferred from one body to another as a result of the difference in temperature while temperature is the measure of the degree of hotness or coldness of a body.
Let us take a look into other key differences.
DIFFERENCE BETWEEN HEAT AND TEMPERATURE
HEAT | TEMPERATURE |
|
|---|---|---|
| 1. | Heat is a form of energy that is transferred from one body to another as a result of difference in temperature. | Temperature is the measure of the degree of hotness or coldness of a body. |
| 2. | The total energy (kinetic energy and potential energy) obtained by molecules in an object. | The average kinetic energy of molecules in an object. |
| 3. | an extensive property | An intensive property |
| 4. | Flows from hot body to cold body. | Rises when the object is heated and falls when cooled down. |
| 5. | Measured by the calorimeter. | Measured by the thermometer. |
| 6. | Has a working ability. | Does not have working ability. |
| 7. | S.I unit is Joules (J) | It’s S.I unit is Kelvin (K), Celsius (C) or Fahrenheit (F) |
| 8. | Represented by “Q”. | Represented by “T”. |
| 9. | It is a vector quantity | It is a scaler quantity |

If two objects with different temperatures are brought in contact, they will be heat transfer between them.
This could go on until thermal equilibrium is reached.
Heat energy is also known as thermal energy.
If the thermal energy is increased, the temperature of the object will rise and thermal equilibrium will be reached in a shorter time.
From this, we can deduce that thermal energy is directly proportional to temperature.
