Internal energy of a gas remains unchanged I. an isothermal process II. an adiabatic process III. a reversible process IV. a cyclic process Which of these are true?
Options
- AI and IV
- BI, III and IV
- CIII and IV
- DII and III
Correct answer
A. I and IV
Step-by-step solution
For isothermal process, d U=0 , i.e., internal energy remains unchanged. For a cyclic process, d U=0 , i.e., internal energy remains unchanged.
