1.	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.
Answer» The volume of the condensed vapour was originally `V_0 - V` at temperature `T = 373 K`. Its mass will be given by `p(V_0 - V) = (m)/(M) RT` or `m = (Mp(V_0 - V))/(RT) = 2 gm` where `p = `atmospheric pressure.
