The volume of gas is reduced to half from its original volume. The specific heat will

A

reduced to half

B

be doubled

C

remain constant

D

increased four times

Text Solution

Verified by Experts

The correct Answer is:
C

The specific heat of a substance is the heat required to raise the temperature of 1 gram of a substance by one degree `(1 K or 1^(@)C)`. It is an intensive property and is independent of the volume of the substance.
