An ideal monoatomic gas is taken round the cycle $ABCDA$ shown in the $PV$ diagram. The work done during the cycle is

$A$ monoatomic gas is taken along path $AB$ as shown in the $V-P$ diagram. Calculate the change in internal energy of the system.

The given diagram shows an ideal gas taken from state $1$ to $2$ through three different paths $A, B,$ and $C$. Let $Q, W,$ and $\Delta U$ represent the heat supplied to the gas,the work done by the gas,and the change in internal energy of the gas,respectively. Then which of the following conditions is true?

An ideal gas is taken from point $A$ to the point $B,$ as shown in the $P-V$ diagram. The work done in the process is

$A$ thermodynamic system is taken through the closed cycle $PQRSP$ process as shown in the figure. The net work done by the system is ...... $J$.

The graph shows a $P-V$ diagram where $A-B$ is an adiabatic curve. Choose the correct statement regarding the processes $AC$ and $BC$.
