Which of the following statement(s) is/are true? "Internal energy of an ideal gas
- A. Decreases in an isobaric process
- B. Remains constant in an isothermal process
- C. Increases in an isobaric process
- D. Decreases in an isobaric expansion
Step-by-step solution
For an ideal gas, internal energy depends only on temperature. In an isothermal process, temperature is constant, so internal energy remains constant. Options A and C are not universally true for all isobaric processes, as internal energy can increase or decrease. Option D is false because isobaric expansion increases temperature and thus internal energy.
