Q1: In saturated gas, the

ANS:A - vapour is in equilibrium with the liquid at the gas temperature.

In saturated gas, the vapour is in equilibrium with the liquid at the gas temperature. When a gas is saturated with vapor, it means that the gas contains the maximum amount of vapor that it can hold at a given temperature and pressure. At this point, the vapor and liquid phases are in equilibrium, meaning that there is a dynamic balance between the rate of evaporation (from the liquid phase to the vapor phase) and the rate of condensation (from the vapor phase to the liquid phase). Therefore, in a saturated gas, the vapor is in equilibrium with the liquid at the same temperature as the gas. This equilibrium condition ensures that the partial pressure of the vapor in the gas phase is equal to the vapor pressure of the liquid at that temperature, allowing for the establishment of dynamic equilibrium between the two phases. So, the correct statement is: vapour is in equilibrium with the liquid at the gas temperature.
