Molecular Speeds & Maxwell Distribution question from JEE Main 2024 (31 Jan, Shift 1)

Q26JEE Main 2024 · 31 JAN · SHIFT 1Easy

Molecular Speeds & Maxwell Distribution

The parameter that remains the same for molecules of all gases at a given temperature is:

Show answer and solution

Answer: (a)

Average KE per molecule $= \frac{3}{2}kT$ (translational) is the same for all gases at the same $T$ .
Mass, momentum and speed depend on the molecular mass.
So the answer is (a) kinetic energy.
