$\Delta W = 0$,for the process

Work done by air when it expands from $50 \, L$ to $150 \, L$ at a constant pressure of $2 \, atm$ is:

Two moles of helium gas are taken over the cycle $ABCDA$,as shown in the $P-T$ diagram. Assuming the gas to be ideal,the work done on the gas in taking it from $A$ to $B$ is ...... $R$.

In an isochoric process,if ${T_1} = {27^o}C$ and ${T_2} = {127^o}C$,then ${P_1}/{P_2}$ will be equal to:

Which of the following graphs between pressure $(P)$ and volume $(V)$ of a gas correctly shows an isochoric process in thermodynamics?

In a reversible isochoric change,
