One mole of a certain ideal gas is contained under a weight-less piston of a vertical cylinder at a temperature `T`. The space over the piston opens into the atmosphere. What work has to be performed on order to increase isothermally the gas volume under the piston `n` times by slowly raising the piston ? The friction of the piston against the cylinder walls is negligibly small.

One mole of a gas is put under a weightless piston of a vertical cylinder at temperature T. The space over the piston opens into atmosphere. Initially, piston was in equilibrium. How much work should be performed by some external force to increase isothermally the volume under the piston to twice the volume? (Neglect friction of piston).

One mole of an ideal gas is contained with in a cylinder by a frictionless piston and is initially at temperature T. The pressure of the gas is kept constant while it is heated and its volume doubles. If R is molar gas constant, the work done by the gas in increasing its volume is

A piston can freely move inside a horizontal cylinder closed from both ends. Initially, the piston separates the inside space of the cylinder into two equal parts each of volmek V_0 in which an ideal gas is contained under the same pressure p_0 and at the same temperature. What work has to be performed in order to increase isothermally the volume of one part of gas eta times compared to that of the other by slowly moving the piston ?

Two moles of an ideal gas is contained in a cylinder fitted with a frictionless movalbe piston, exposed to the atmosphere, at an initial temperature T_(0) . The gas is slowly heated so that its volume becomes fout times the initial value. The wor done by gas is

One mole of an ideal gas is contained in a vertical cylinder under a massless piston moving without friction. The piston is slowly raised so that the gas expands isothermally at temperature T_0 = 300 K. Find the amount of work done increasing the volume to eta =2 times. The outside pressure is atmospheric.

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.
