For one complete cycle of a thermodynamic process on a gas as shown in the $P-V$ diagram,which of the following is true?

One mole of an ideal monoatomic gas is taken along the path $ABCA$ as shown in the $PV$ diagram. The maximum temperature attained by the gas along the path $BC$ is given by

An ideal gas is taken through the path $A \rightarrow B \rightarrow C \rightarrow A$ as shown in the figure. The net work done by the gas is ....... $J$.

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

An ideal gas undergoes the cyclic process $abca$ as shown in the given $P-V$ diagram. It rejects $50 \,J$ of heat during $ab$ and absorbs $80 \,J$ of heat during $ca$. During $bc$, there is no transfer of heat and $40 \,J$ of work is done by the gas. What should be the area of the closed curve $abca$ (in $\,J$)?

The $P-V$ diagrams for a particular gas undergoing different thermodynamic processes are given below. Identify the correct statement.
