The $P-V$ diagram shows seven curved paths (connected by vertical paths) that can be followed by a gas. Which two of them should be parts of a closed cycle if the net work done by the gas is to be at its maximum value?

The net work done by an ideal gas going through the cycle as shown in the $P-V$ diagram below is

Six moles of an ideal gas perform the cycle shown in the figure. If the temperatures are $T_A = 600 \, K$, $T_B = 800 \, K$, $T_C = 2200 \, K$, and $T_D = 1200 \, K$, the work done per cycle is ........ $kJ$.

An ideal gas is taken through the cycle $A \to B \to C \to A,$ as shown in the figure. What is the change in internal energy in $J$?

$A$ 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 $\text{ J}$)

On a $TP$ diagram,two moles of an ideal gas perform processes $AB$ and $CD$. If the work done by the gas in the process $AB$ is two times the work done in the process $CD$,then what is the value of $T_1/T_2$?
