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?

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.

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.

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 non conducting vessel thermally insulated from its surroundings, contains 100 g of water 0^(@)C . The vessel is connected to a vacuum pump to pump to water vapour. As a result of this, some water is frozen. If the removal of water vapour is continued, what is the maximum amount of water that can be frozen in this manner? Laten heat of vaporisation of water =22.5xx10^(5)Jkg^(-1) and latent heat of fusion of ice =3.36xx10^(5)Jkg^(-1)

A gas is contained in a vessel fitted with a movable piston. The container is placed on a stove. A total of 100 cal of heat is given to the gas and the gas does 40 J of work in the expansion resulting from heating. Calculate the increase in internal energy in the process.

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.

Figure shows a cylinder closed by a movable piston containing an ideal gas. The piston is quickly pushed down from position 2. The piston is held at position 2 until the gas is again at 0^(@)C and then is slowly raised back to position 1. Represent the whole operation on a P-V diagram. If 100 g of ice melts during the cycle, how much work is done on the gas?
