For an ideal gas, the internal energy depends upon its ____________ only?
Correct answer: B. Temperature
- A. Molecular size
- B. Temperature
- C. Volume
- D. Pressure
Explanation
For an ideal gas, intermolecular effects are absent, so internal energy is a function of temperature alone, U = U(T). Pressure and volume may change independently while temperature remains fixed without changing the internal energy.
