JEE Main 2024 Physics question
Given below are two statements: Statement (I): The mean free path of gas molecules is inversely proportional to square of molecular diameter. Statement (II): Average kinetic energy of gas molecules is directly proportional to absolute temperature of gas. In the light of the above statements, choose the correct answer from the option given below:
Answer: (D)
Solution
λ = 1/(√2πnd²) ∝ 1/d² and the average KE = (3/.
