What is the factor upon which change in internal energy of an ideal gas depends?
Correct answer: C. Change in temperature
- A. Change in volume
- B. Change in temperature and volume
- C. Change in temperature
- D. Path followed to change internal energy
Explanation
The internal energy of an ideal gas depends solely on its temperature. According to the ideal gas law and the kinetic theory of gases, the internal energy of an ideal gas is directly proportional to its temperature. When the temperature of an ideal gas changes, its internal energy also changes.

About First Law of Thermodynamics
The first law relates heat supplied, work done and the change in internal energy through energy conservation. Problems use sign conventions and apply the law to isothermal, adiabatic, isobaric and isochoric processes. Internal energy is a state function, while heat and work depend on the path followed.
