In the P-V diagram below the dashed curved line is an adiabat, 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 : (hint : Consider the variations in temperature from X to Y along the straitght line)

Options

  1. Aabsorbed throughtout from X to Y
  2. Breleased throughout from X to Y
  3. Cabsorbed from X up to an intermediate point Z (not shown in the figure) and then released from Z to Y
  4. Dreleased from X up to an intermediate point Z (not shown in the figure) and then absorbed from Z to Y

Correct answer

C. absorbed from X up to an intermediate point Z (not shown in the figure) and then released from Z to Y
