Match the List-I with List-II List-I A. Pressure varies inversely with volume of an ideal gas. B. Heat absorbed goes partly to increase internal energy and partly to do work. C. Heat is neither absorbed nor released by a system. D. No work is done on or by a gas List-II I. Adiabatic process II. Isochoric process III. Isothermal process IV. Isobaric process Choose the correct answer from the options given below :

1. A-I, B-IV, C-II, D-III
2. A-III, B-I, C-IV, D-II
3. A-I, B-III, C-II, D-IV
4. A-III, B-IV, C-I, D-II

Correct answer: A-III, B-IV, C-I, D-II

Solution

The correct matches reflect fundamental gas laws and thermodynamic processes: A (Pressure and volume relationship) aligns with isothermal processes where pressure varies inversely with volume; B (Heat absorbed) corresponds to isobaric processes where heat is used for work; C (No heat exchange) describes an adiabatic process; and D (No work done) fits with isochoric processes where volume remains constant.
