The pressure acting on a gas in a cylinder was changed steadily while the temperature of the gas was maintained constant. The value of volume V of the gas was measured for various values of pressure. The graph in Figure 11 shows the relation between the pressure P, and the reciprocal of volume, $\frac{1}{V}$

(i) By changing pressure very slowly or by allowing gas to go to original temperature after the change.

(ii) k represents work done on the gas.

(iii) - Use dry gas

- Make very small changes in temperature.
