An ideal gas has undergone a cyclic process as shown in the figure. The work done by the gas in the entire cycle is . . . . . . $\times 10^{-1} \ J$. (Take $\pi = 3.14$)

The pressure of a gas changes linearly with volume from $A$ to $B$ as shown in the figure. If no heat is supplied to or extracted from the gas,then the change in the internal energy of the gas will be $............\,J$.

An ideal gas is taken around the cycle $ABCA$ as shown in the $P-V$ diagram. The work done during the cycle is

$A$ thermodynamic system is taken through a cyclic process as shown in the $P-V$ diagram. The total work done in the process is $.........\,J$.

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?

The work done in the cyclic process $PQRSP$ shown in the figure is .......... $J$.
