What is saturation pressure ?

Text Solution

AI Generated Solution

### Step-by-Step Solution: 1. **Definition of Saturation Pressure**: - Saturation pressure is defined as the pressure exerted by a vapor in equilibrium with its liquid (or solid) phase at a given temperature. At this pressure, the rate of evaporation of the liquid equals the rate of condensation of the vapor. 2. **Equilibrium Condition**: - At saturation pressure, the system is in a state of equilibrium, meaning that the amount of liquid evaporating into vapor is equal to the amount of vapor condensing back into liquid. This balance ensures that the number of molecules in both phases remains constant over time. ...
