Question

Match each process in List I with the specific heat in List II.

List I	List II
(A) Water boiling at 100°C	(P) Infinite
(B) Isothermal expansion of an ideal gas	(Q) Zero
(C) Adiabatic process	(R) Finite, equal to $C_{v}$ for a gas
(D) Heating a gas at constant volume	(S) Negative

TestHub · Accepted Answer

Boiling water and isothermal expansion of an ideal gas both

absorb heat at constant temperature, so $c \to \infty$ (P).

Adiabatic process: $Q = 0$ , so $c = 0$ (Q). Constant volume: $c = C_{v}$

(R). Option C matches A-P, B-P, C-Q, D-R.
