In this \((P\text -V)\) diagram below the dashed curved line is adiabatic.

For a process, that is described by a straight line joining two points \(X\) and \(Y\) on the adiabat (solid line In the diagram) heat is:
(consider the variations in temperature from \(X\) to \(Y\) along the straight line.)

1. absorbed throughout from \(X\) to \(Y.\)
2. released throughout from \(X\) to \(Y.\)
3. absorbed from \(X\) up to an intermediate point \(Z\) (not shown In the figure) and then released from \(Z\) to \(Y.\)
4. released from \(X\) up to an Intermediate point \(Z\) (not shown in the figure) and then absorbed from \(Z\) to \(Y.\)

A gas expands from \(i\) to \(f\) along the three paths indicated. The work done along the three paths denoted by \(W_1, W_2, ~\text{and}~W_3\) have the relationship:
          
1. \(W_1<W_2<W_3\) 2. \(W_2<W_1=W_3\)
3. \(W_2<W_1<W_3\) 4. \(W_1>W_2>W_3\)
