Internal energy of an ideal gas depends on:
Correct answer: B. Temperature
- A. Volume
- B. Temperature
- C. Pressure
- D. Path followed
Explanation
According to the ideal gas law, the internal energy of an ideal gas depends only on its temperature. It is independent of volume, pressure, or the path followed during the process.

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.
