MCQ
Which of the following statements is correct?
- AA gas has two specific heats only
- ✓A gas has infinite number of specific heats
- CA material will have only one specific heat always
- DNone of the above
✓
Answer
Correct option: B.
A gas has infinite number of specific heats
b
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.
