In a reversible isochoric change,

$A$ diatomic gas $(\gamma = 1.4)$ does $300 \ J$ of work when expanded isobarically. The heat given to the gas in this process is: (in $J$)

In thermodynamics,for an isochoric process,which one of the following statements is $INCORRECT$?

The ratio of specific heats of a gas is $\gamma$. The change in internal energy of one mole of the gas,when the volume changes from $V$ to $2V$ at constant pressure $p$,is:

$A$ vessel contains an ideal monoatomic gas which expands at constant pressure,when heat $Q$ is given to it. Then the work done in expansion is:

$A$ diatomic gas,having $C_{p} = \frac{7}{2} R$ and $C_{v} = \frac{5}{2} R$,is heated at constant pressure. The ratio $dU : dQ : dW$ is:
