Statement I: The temperature of a non-ideal gas does not change in adiabatic free expansion. Stateme — Thermodynamics and Thermochemistry Chemistry Question
Question
Statement I: The temperature of a non-ideal gas does not change in adiabatic free expansion. Statement II: In adiabatic free expansion of ideal as well as non-ideal gas, q = w = ΔU = 0.
Answer: D
💡 Solution & Explanation
Statement I incorrect (real gases cool during free expansion due to intermolecular attractions). Statement II correct (for any free expansion: w = 0; adiabatic: q = 0; so ΔU = 0).
