Which of the following statements is correct?

A

A gas has two specific heats only

B

A gas has infinite number of specific heats

C

A material will have only one specific heat always

D

None of the above

Solution

Specific heat of a gas is the amount of heat required to increases the temperature of one mole of the gas through unit degre. During different possesses, the work done by a gas may be different. Hence, specific heat of a gas depends on the process followed. Since, number of processes which are possible is infinite, therefore, a gas has an infinite number of specific heats. Therefore, option $(2)$ is correct.
