Statement I: The heat absorbed during the isothermal expansion of an ideal gas against vacuum is zer — Thermodynamics and Thermochemistry Chemistry Question
Question
Statement I: The heat absorbed during the isothermal expansion of an ideal gas against vacuum is zero. Statement II: The volume occupied by the molecules of an ideal gas is negligible.
Answer: B
💡 Solution & Explanation
Statement I correct (ΔU = 0, w = 0 for free expansion, so q = 0). Statement II correct as kinetic theory assumption, but doesn't explain Statement I.
