The given diagram shows four processes,i.e.,isochoric,isobaric,isothermal,and adiabatic. The correct assignment of the processes,in the same order,is given by

$A$ constant amount of an ideal gas undergoes the cyclic process $ABCA$ in the $p-V$ graph shown below. The path $BC$ is an isothermal process. The work done by the gas during one complete cycle,beginning and ending at $A$,is nearly .......... $kJ$.

Two moles of an ideal monoatomic gas undergo a cyclic process as shown in the figure. The temperatures in different states are given as $6 T_1 = 3 T_2 = 2 T_4 = T_3 = 2400 \text{ K}$. The work done by the gas during the complete cycle is $(R = \text{Universal gas constant})$ (in $R$)

$A$ cyclic process $ABCD$ is shown below in the given $P-V$ diagram. Which of the following diagrams represents the same process in a $P-T$ diagram?

An ideal gas undergoes a cyclic process as shown in the diagram. The net work done by the gas in the cycle is

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