In the $P-V$ diagram, $I$ is the initial state and $F$ is the final state. The gas goes from $I$ to $F$ by $(i)\,IAF,\,\,(ii)\,IBF,\,\,(iii) ICF$. The heat absorbed by the gas is

Heat energy absorbed by a system in going through a cyclic process shown in figure is

An ideal gas undergoes a circular cycle centred at $4 \,atm , 4 L$ as shown in the diagram. The maximum temperature attained in this process is close to

When a system is taken from state $i$ to a state $f$ along path $iaf, \,Q = 50\,J$ and $W = 20J.$ Along path $ibf, \,Q = 35J.$ If $W = – 13J$ for the curved return path $f i, Q$ for this path is …… $J$

An ideal gas is taken through the cycle $A \to B \to C \to A$ , as shown in the figure. If the net heat supplied to the gas in the cycle is $5\ J$, the work done by the gas in the process $C \to A$ is  …. $J$
