Revision Notes — Kinetic Theory
Key concepts, formulas, and definitions from Kinetic Theory for CUET (UG) Physics preparation.
Key Topics to Revise
12.2 Molecular Nature of Matter
- Feynman's atomic hypothesis: All things are made of atoms in perpetual motion
- John Dalton's Atomic Theory: Compounds have fixed proportions by mass
- Gay-Lussac's Law: Gas volumes combine in simple integer ratios
12.3 Behavior of Gases
- Ideal gas equation: PV = μRT = NkBT
- Boyle's Law: At constant T, PV = constant
- Charles' Law: At constant P, V ∝ T
12.4 Kinetic Theory of an Ideal Gas
- Gas molecules are in constant random motion
- Intermolecular forces are negligible except during collisions
- Collisions are perfectly elastic
12.4 Maxwell's Distribution of Molecular Speeds
- Molecules have a range of speeds, not single speed
- Maxwell's distribution gives fraction of molecules at each speed
- Three characteristic speeds: most probable (vmp), average (vav), and rms (vrms)
