An ideal gas undergoes a cyclic process $ABCDA$ as shown in the given $p-V$ diagram. What is the magnitude of the amount of work done by the gas?

$A$ sample of an ideal monoatomic gas is taken around the cycle $ABCA$ as shown in the figure. The work done during the cycle is

What is the nature of the change in internal energy for the following three thermodynamic processes shown in the figure?

The $P-V$ diagram shown below indicates two paths along which a sample of gas can be taken from state $A$ to state $B$. The energy equal to $5PV$ in the form of heat is required to be transferred if Path-$1$ is chosen. How much energy in the form of heat should be transferred if Path-$2$ is chosen?

In the given $P-V$ diagram,the initial state of an ideal gas is represented by point $a$ and the final state by point $e$. The gas moves from state $a$ to state $e$ along paths $(i) abe, (ii) ace, (iii) ade$. The heat absorbed by the gas will be:

An ideal gas follows the path shown in the figure. The net work done in the whole cycle is
