The internal energy of an ideal gas depends upon its:
Correct answer: D. Temperature only
- A. Molecular size
- B. Pressure only.
- C. Volume only
- D. Temperature only
Explanation
In an ideal gas, the inter-molecular collisions are assumed to be absent and the collisions are perfectly elastic. Thus, the gas possesses only translational kinetic energy and hence the internal energy of the ideal gas depends only on temperature.

About Internal Energy
Internal energy is the total microscopic kinetic and potential energy of a system and is a state function. The first law, ΔU = q + w, connects changes in internal energy with heat and work, including sign conventions, expansion or compression and constant-volume processes.
