| Statement I It is convenient to define two specific heats \[{{C}_{p}}\] and \[{{C}_{V}}\] in case of a gas. However it is not generally necessary to define two specific heats in case of a solid or liquid |
| Statement II For a given temperature rise, the expansion of a solid or liquid is negligible as compared to that of a gas. |
A) Statement-1 is True, Statement-2 is True; Statement-2 is a correct explanation for Statement-1
B) Statement-1 is True, Statement-2 is 'I rue; Statement-2 is NOT a correct explanation for Statement-1
C) Statement-1 is True, Statement-2 is False
D) Statement-1 is False, Statement-2 is True
Correct Answer: A
Solution :
Statement-1: \[C{{ & }_{P}}\And \,{{C}_{{{C}_{V}}}}\] for gases only solid and liquids do not expand much as compared to gases. Hence we do not generally define \[{{C}_{P}}\] and \[{{C}_{V}}\] for solids and liquids. Statement-2: correct explanation.
