One mole of water being in equilibrium with a negligible amount of its saturated vapour at a temperature `T_1` was completely converted into saturated vapour at a temperature `T_2`. Find the entropy increment of the system. The vapour is assumed to be an ideal gas, the specific volume of the liquid is negligible on comparsion with that of the vapour.

A small amount of water and its saturated vapour are enclosed in a vessel at a temperature t = 100^@C . How much (in per cent) will the mass of the saturated vapour increase if the temperature of the system goes up by Delta T = 1.5 K ? Assume that the vapour is an ideal gas and the specific volume of water is negligible as compared to that vapour.

One mole of a Van der Waals gas which had initially the volume V_1 and the temperature T_1 was transferred to the state with the volume V_2 and the temperature T_2 . Find the corresponding entropy increment of the gas, assuming its molar heat capacity C_V to be known.

A liquid is in equilibrium with its vapour in a sealed container at a fixed temperature. The volume of the container is suddenly increased.

An amount of water of mass m = 1.00 kg , boiling at standard atmospheric pressure, turns completely into saturated vapour. Assuming the saturated vapour to be an ideal gas find the increment of entropy and internal of the system.

When a given volume of air contains maximum possible amount of water vapour, it is said to be saturated with vapour at that temperature.

When a given volume of air contains maximum possible amount of water vapour, it is said to be saturated with vapour at that temperature.

Water remains in equilibrium with its vapour at 100^(@)C and 1 atm. Will the transformation of water into its vapour be spontaneous at this pressure and temperature?

A water vapour filling the space under the piston of a cylinder is compressed (or expanded) so that it remaind saturated all the time, being just on the verge of condensation. Find the molar heat capacity C of the vapour in this process as a function of temperature T , assuming the vapour to be an ideal gas and neglecting the specific volume of water in comparion with that of vapour. Calculate C at a temperature t = 100 ^@C .
