An ideal gas of mass $m$ in a state $A$ goes to another state $B$ via three different processes as shown in the figure. If $Q_{1}, Q_{2}$,and $Q_{3}$ denote the heat absorbed by the gas along the three paths,then

In the given $PV$ diagram,a system goes from state $P$ to state $Q$ along two different paths. Along path $1$,the system is given $1000 \ J$ of heat. The work done by the system along path $1$ is $100 \ J$ more than the work done along path $2$. How much heat is transferred along path $2$ (in $J$)?

$A$ system goes from $A$ to $B$ via two processes $I$ and $II$ as shown in the figure. If $\Delta U_I$ and $\Delta U_{II}$ are the changes in internal energies in the processes $I$ and $II$ respectively,then:

Four curves $A, B, C$ and $D$ are drawn in the adjoining figure for a given amount of an ideal gas. The curves which represent adiabatic and isothermal expansions, respectively, are

Three moles of an ideal monoatomic gas undergo a cyclic process as shown in the figure. The temperatures of the gas in different states marked as $1, 2, 3$ and $4$ are $400 \ K, 700 \ K, 2500 \ K$ and $1100 \ K$ respectively. The work done by the gas during the process $1-2-3-4-1$ is (universal gas constant is $R$): (in $R$)

In the cyclic process shown in the figure,the work done by the gas in one cycle is (in $,{P_1}{V_1}$)
