Q. No.An ideal gas goes through a reversible cycle \({a}\rightarrow{b}\rightarrow{c}\rightarrow{d}\) has the \({V \text- T}\) diagram as shown below. Process \({d}\rightarrow{a}\) and \({b}\rightarrow{c}\) are adiabatic.
The corresponding \({P \text- V}\) diagram for the process is (all figures are schematic and not drawn to scale):

A sample of an ideal gas is taken through the cyclic process \(ABCA\) as shown in the figure. It absorbs, \(40~\text{J}\) of heat during part \(AB\), no heat during \(BC\), and rejects \(60~\text{J}\) of heat during \(CA\). A work of \(50~\text{J}\) is done on the gas during part \(BC\). The internal energy of the gas at \(A\) is \(1560~\text{J}\). The work done by the gas during the part \(CA\) is:
1. \(20~\text{J}\)
2. \(30~\text{J}\)
3. \(-30~\text{J}\)
4. \(-60~\text{J}\)
1. \(20~\text{J}\)
2. \(30~\text{J}\)
3. \(-30~\text{J}\)
4. \(-60~\text{J}\)
