Molarity is a function of temperature because:
| 1. | Volume depends on temperature and molarity involves volume. |
| 2. | Molarity involves non-volatile solutes while all other terms involve volatile solutes. |
| 3. | Number of moles of solute changes with a change in temperature. |
| 4. | Molarity is used for polar solvents only. |
