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.

A saturated water vapour is contained in a cylindrical vessel under a weightless piston at a temperature t = 100 ^@C . As a result of a slow introduction of the piston a small fraction of the vapour Delta m = 0.70 g gets condensed. What amount of work was perfomed over the gas ? The vapour is assumed to be ideal, the volume of the liquid is to be neglected.

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

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.

A cylinder closed by a piston contains 8 g of water vapour at a temperature of 55^(@)C . The vapour is compressed isothermally. What will be its volume when dew begins to appear?

One gram of saturated water vapour is enclosed in a thermally insulated cylinder ubder a weightless piston. The outside pressure being standard, m = 1.0 g of water is introduced into the cylinder at a temperature t_0 = 22 ^@C . Neglecting the heat capacity of the cylinder and the friction of the piston against the cylinder's walls, find the work performed by the force of the atmospheric pressure during the lowering of the piston.

One mole of a perfect gas in a cylinder fitted with a piston has a pressure P, volume V and temperature T. if the temperature is increased by 1K keeping pressure constant, the increase in volume is

A saturated water vaporu (M=18) is contained in a vessel fitted with a piston at a temeprature t=100^(@)C . As a result of slow introduction of the piston a small fractioin of the vapour Deltam=1g gets condensed. What amount of work is done over the gas?
