$A$ thermodynamic system undergoes a cyclic process $ABCDA$ as shown in the figure. The work done by the system in the cycle is

Which of the curves in the given $P-V$ diagram represents an adiabatic process and an isothermal process,respectively?

Calculate the heat given to the gas during the cyclic process $ABA$ shown in the figure (in $J$).

In the given $PV$ diagram,a system goes from state $P$ to state $Q$ along two different paths. Along path $1$,the system is given $1000 \ J$ of heat. The work done by the system along path $1$ is $100 \ J$ more than the work done along path $2$. How much heat is transferred along path $2$ (in $J$)?

The $P-V$ diagram shows a cyclic process for a thermodynamic engine containing a monoatomic ideal gas. The energy absorbed from the heat source during one complete cycle is .......

$A$ thermodynamic system is taken through the cyclic process $ABC$ as shown in the figure ($P-V$ graph: $A(2, 100)$, $B(5, 300)$, $C(5, 100)$). The total work done by the system during the cycle $ABC$ is . . . . . . $J$.
