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.

Assuming the saturated water vapour to be ideal, find its pressure at the temperature 101.1 ^@C .

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 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 .

Calculate the volume of 3.6g of water vapour at 273K temperature and 1 atm pressure.

The saturated water vapour is inclosed in a cylinder under a piston and occupies a volume V_0 = 5.0 1 at the temperature t = 100 ^@C . Find the mass of the liquid phase formed after the volume under the piston decreased isothermally to V = 1.6 1 . The saturated vapour is assumed to be ideal.

10 Its of an air sample with relative humidity 0.6 is compressed to 5 litres at same temperature. What is the partial pressure of the water vapour in the compressed air, if the pressure of saturated water vapour at that temperature is 2.4 K Pa
