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

In a thermodynamic process,the pressures and volumes corresponding to some points in the figure are $P_A = 3 \times 10^4 \, Pa$,$V_A = 2 \times 10^{-3} \, m^3$,$P_B = 8 \times 10^4 \, Pa$,and $V_D = 5 \times 10^{-3} \, m^3$. In process $AB$,$600 \, J$ of heat is added,and in process $BC$,$200 \, J$ of heat is added to the system. The change in the internal energy in process $AC$ would be .... $J$.

The work done by a gas as it is taken in a cyclic process (shown in the graph) is (in $PV$)

$A$ gas is taken through the cycle $A \to B \to C \to A$ as shown in the figure. What is the net work done by the gas in $J$?

The adjoining figure shows the $P-V$ diagram for a fixed mass of an ideal gas undergoing a cyclic process. $AB$ represents an isothermal process and $CA$ represents an isochoric process. Which of the graphs shown in the following figures represents the $P-T$ diagram of the cyclic process?

An ideal gas undergoes a change in its state from the initial state $I$ to the final state $F$ via two possible paths as shown below. Then,
