$A$ sample of ideal gas $(\gamma = 1.4)$ is heated at constant pressure. If $100 \ J$ of heat is supplied to the gas,the work done by the gas is ...... $J$.

How much work is to be done in decreasing the volume of an ideal gas by an amount of $2.4 \times 10^{-4} \ m^3$ at normal temperature and constant normal pressure of $1 \times 10^5 \ N/m^2$ (in $J$)?

$A$ diatomic ideal gas undergoes a thermodynamic change according to the $P-V$ diagram shown in the figure. The heat given to the gas in process $AB$ is: (in $, P_0 V_0$)

Describe the nature of $P-V$ diagrams for isobaric and isochoric processes.

Write the expression for the work done by an ideal gas in an isobaric process.

Work done by $0.1$ mole of a gas at $27^{\circ}C$ to double its volume at constant pressure is ....... $cal$ $(R = 2 \, cal \, mol^{-1} \, K^{-1})$.
