Question Style in MHT CET Kinetic Theory of Gases PYQs

Every question in this PDF is a single-correct MCQ. About half need the r.m.s. speed formula, and most others are short numerical questions.

Question Style	What it Tests
r.m.s. speed	The r.m.s. speed at 800 K, hydrogen compared with oxygen, and the temperature at which the r.m.s. speed doubles or reaches a given multiple
Ideal gas and temperature change	A gas cooled until its pressure and volume are both halved, and an ideal gas heated at constant pressure from 27 °C to 627 °C
Molecules of different gases	N molecules of gas A and 2N molecules of gas B with different molecular masses in the same jar
Mean free path	The mean free path of a gas molecule at S.T.P. in terms of its diameter
Kinetic energy and specific heat	The average kinetic energy of a molecule, and the molecules of a gas for which C_V = 0.4 R

How to Use the Kinetic Theory of Gases PYQ PDF for MHT CET

Start with the 2025 and 2026 papers first, because they hold 8 of the 25 questions.
Learn v_rms = √(3RT/M) and use ratios, since most questions compare two gases or two temperatures.
For the temperature questions, convert to kelvin first.
Solve year-wise PYQs by timing yourself, as time management is crucial.
Re-attempt only the questions you got wrong, and note which formula or step you missed.
