An ideal gas is made to undergo a cycle depicted by the PV diagram alongside. The curved line from A to B is an adiabat. Then-

Options

  1. AThe efficiency of this cycle is given by unity as no heat is released during the cycle
  2. BHeat is absorbed in the upper part of the straight line path and released in the lower part
  3. CIf T₁ and T₂ are the maximum and minimum temperatures reached during the cycle, then the efficiency is given b
  4. DThe cycle can only be carried out in the reverse of the direction shown in figure

Correct answer

B. Heat is absorbed in the upper part of the straight line path and released in the lower part

Step-by-step solution

From the analysis of P - V diagram we can easily say that B is the correct option.
