$A$ gas expands by $0.25 \ m^{3}$ at a constant pressure of $10^{3} \ N/m^{2}$. Calculate the work done.

$A$ diatomic gas $\left(C_P = \frac{7}{2} R\right)$ does $200 \ J$ of work when it is expanded isobarically. The heat given to the gas in the process is (in $J$)

$A$ monoatomic gas is heated at constant pressure. The percentage of total heat used for doing external work is (in $\%$)

$A$ container having $1 \ mol$ of a gas at a temperature of $27 \ ^oC$ has a movable piston which maintains a constant pressure of $1 \ atm$ in the container. The gas is compressed until the temperature becomes $127 \ ^oC$. The work done is ........ $J$ $(R = 8.31 \ J/mol-K)$.

$A$ sample of a gas expands from volume $V_1$ to $V_2$. The amount of work done by the gas is maximum when the expansion is:

The work done by a gas is maximum when it expands from a volume $V_1$ to $V_2$. This expansion is:
