$A$ 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 . . . . . . $J$.

As shown in the figure,the amount of heat absorbed along the path $ABC$ is $90\,J$ and the amount of work done by the system is $30\,J$. If the amount of work done along the path $ADC$ is $20\,J$,the amount of heat absorbed will be .... $J$.

An ideal gas undergoes a four-step cycle as shown in the $P-V$ diagram below. During this cycle,in which step is heat absorbed by the gas?

$A$ thermodynamic system is taken from an original state $D$ to an intermediate state $E$ by the linear process shown in the figure. Its volume is then reduced to the original volume from $E$ to $F$ by an isobaric process. The total work done by the gas from $D$ to $E$ to $F$ will be $......J$

$n$ moles of an ideal gas undergo a process $A \to B$ as shown in the figure. The maximum temperature of the gas during the process is

One mole of an ideal monoatomic gas is taken round the cyclic process $MNOM$. The work done by the gas is (in $p_0 V_0$)
