An ideal gas undergoes a process where its molar heat capacity is . If the gas is monatomic, what is the work done by the gas when its temperature increases by ?
- A.
- B.
- C.
- D.
Show correct answer & step-by-step solution
Correct answer: C —
Solution
Using the first law , we have . For monatomic gas , so . The magnitude of work done by the gas is in the opposite direction, but given the options, we evaluate the energy balance.
