Statement 1: A gas has a unique value of specific heat.
Statement 2: Specific heat is defined as the amount of heat required to raise the temperature of unit mass of the substance through unit degree.

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 true, Statement-2 is NOT a correct explanation for Statement-1.

C

Statement-1 is true but statement-2 is false

D

Statement-1 is false, Statement-2 is true

Text Solution

Verified by Experts

The correct Answer is:
D

This is because a gas can be heated under different conditions of pressure and volume. The amount of heat required to raise the temperature of unit mass through until degree is different under different conditions of heating.
