Work done in the cyclic process shown in the figure is ...........

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

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

$A$ given mass of a gas expands from a state $A$ to the state $B$ by three paths $1, 2$ and $3$ as shown in the $T-V$ indicator diagram. If $W_1, W_2$ and $W_3$ respectively be the work done by the gas along the three paths,then

$A$ cyclic process $ABCA$ is shown in the $T-V$ diagram. An ideal gas of $2 \text{ mole}$ undergoes this process. $A$ total of $1200 \text{ J}$ of heat is rejected by the gas in the complete cycle. Find the work done by the gas during the process $BC$. (in $\text{ J}$)

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 $............\,J$.
