Thermodynamic Processes

Match the List - I with List - II

Choose the correct answer from the options given below:

List - IList - II
(A)Pressure varies inversely with volume of an ideal gas.(I)Adiabatic process
(B)Heat absorbed goes partly to increase internal energy and partly to do work.(II)Isochoric process
(C)Heat is neither absorbed nor released by a system.(III)Isothermal process
(D)No work is done on or by a gas.(IV)Isobaric process
Show answer and solution

Answer: (d)

  1. P∝1/VP \propto 1/V means PVPV constant: isothermal, (A)-(III).
  2. Heat partly raises UU and partly does work: isobaric, (B)-(IV).
  3. No heat exchanged: adiabatic, (C)-(I).
  4. No work done: VV constant, isochoric, (D)-(II).
  5. So the answer is (d).
