In saturated gas, the__________________?
Correct answer: A. Vapour is in equilibrium with the liquid at the gas temperature
- A. Vapour is in equilibrium with the liquid at the gas temperature
- B. Vapour is in equilibrium with the liquid at the room temperature
- C. Partial pressure of vapour equals the vapour pressure of the liquid at room temperature
- D. None of these
Explanation
A saturated gas contains vapour at equilibrium with the liquid phase at the gas temperature, so its vapour partial pressure equals the saturation pressure at that temperature. Room temperature is relevant only if it is also the gas temperature.
