RMS / Avg / Most-Probable Speeds — Previous-Year Questions
5 previous-year questions on RMS / Avg / Most-Probable Speeds, drawn from JEE Mains, JEE Advanced, NEET UG, and CUET papers. Every question carries a worked-out explanation.
Q1. v_rms of H₂ (M = 2 g/mol) at 300 K:
JEE 2022Q2. Ratio of v_rms of H₂ vs O₂ at same T:
JEE 2021Q3. If T quadruples, v_rms:
JEE 2020Q4. Most probable speed vs RMS speed (same gas, same T):
JEE 2019Q5. If two gases have same v_rms, then:
