A fixed mass m of a gas is subjected to transformation of states from K to L to M to N and back to K as shown in the figure. The succeeding operation that enable this transformation of state are

Options

  1. Aheating, cooling, heating, cooling
  2. Bcooling, heating, cooling , heating
  3. Cheating, cooling, cooling, heating
  4. Dcooling , heating , heating , cooling

Correct answer

C. heating, cooling, cooling, heating

Step-by-step solution

K → L : Isochoric process with increasing in pressure so by T L T K = P L P K P L > P K so T L > T K so it is a case of heating L → M : Isobaric process with increasing in pressure so by T M T L = V M V L V M < V L so T M < T L so it is a case of cooling Similarly for M → N : Isochoric process with increasing in pressure so by T N T M = P N P M P N < P M so T N < T M so it is a case of cooling
