The volume ($$V$$) of a monatomic gas varies with its temperature ($$T$$), as shown in the graph. The ratio of work done by the gas to the heat absorbed by it when it undergoes a change from state $$\mathrm{A}$$ to state $$\mathrm{B}$$ will be:

 1 $$2 \over 5$$ 2 $$2 \over 3$$ 3 $$1 \over 3$$ 4 $$2 \over 7$$

The molar specific heats of an ideal gas at constant pressure and volume are denoted by $$C_P$$ and $$C_V,$$ respectively. If $$\gamma =\frac{C_P}{C_V}$$ and $$R$$ is the universal gas constant, then $$C_V$$ is equal to:
 1 $$\frac{R}{\gamma -1}$$ 2 $$\frac{\gamma -1}{R}$$ 3 $$\gamma R$$ 4 $$\frac{\left ( \gamma -1 \right )R}{\left ( \gamma +1 \right )}$$
