Solids/liquids/gases, phase changes, kinetic theory, gas laws
Pre-med/IB-style questions building mastery of gas behavior: Boyle/Charles/Gay-Lussac/Avogadro laws, PV=nRT, unit traps, STP and molar volume, Dalton’s law and partial pressures (including gas over water), gas stoichiometry with volumes, density and molar mass from gas data, diffusion/effusion, and when real gases deviate from ideal behavior.
