Ncert Exercises & Solutions

Consider a p-V diagram in which the path followed by one mole of a perfect gas in a cylindrical container is shown in the figure.

(a) Find the work done when the gas is taken from state 1 to state 2.

(b) What is the ratio of temperatures $T_{1} / T_{2}$ if $V_{2} = 2 V_{1}$ ?
(c) Given the internal energy for one mole of gas at temperature T is (3/2)RT, find the heat supplied to the gas when it is taken from state 1 to 2 with $V_{2} = 2 V_{1}$ .
