An ideal gas is taken through the cycle $A \to B \to C \to A,$ as shown in the figure. What is the change in internal energy in $J$?

The pressure versus temperature $(P-T)$ graph of an ideal gas is shown in the figure.

What is the total work done in the given $P-V$ graph?

$A$ cyclic process $ABCD$ is shown in the given $P-V$ diagram. In the following answer, the one that represents the same process as in the $P-T$ diagram is:

An ideal gas is taken through the cycle $A \rightarrow B \rightarrow C \rightarrow A$ as shown in the figure. If the net heat supplied to the gas in the cycle is $5 \,J$, the magnitude of work done during the process $C \rightarrow A$ is (in $\,J$)

An ideal monoatomic gas is taken round the cycle $ABCDA$ as shown in the following $P-V$ diagram. The work done during the cycle is
