Which of the following statement(s) is/are correct regarding ideal gas? — Thermodynamics and Thermochemistry Chemistry Question

💡 Solution & Explanation

Point masses (rigid spheres of negligible volume) only possess translational kinetic energy. The total motion of a polyatomic molecule incorporates the independent vector motions of its constituent atoms. Only linear polyatomic molecules strictly have 2 rotational degrees of freedom; non-linear ones have 3.
