Ideal gas model and gas laws

A lesson shell for kinetic assumptions, pressure-volume-temperature relationships, molar volume, and PV=nRT.

Lesson progress
State the assumptions of the ideal gas model.Use matched pressure and volume units in gas calculations.Distinguish single-state ideal gas problems from before/after gas-law comparisons.

The ideal gas model treats gas particles as moving randomly, occupying negligible volume, and colliding elastically.

Ideal gas law
PV = nRT
Key idea

Gas-law calculations require absolute temperature in Kelvin because proportional relationships are defined from absolute zero.
