Kinetic-Molecular Theory's Core Postulates
Captions available
The idea
Kinetic-molecular theory models a gas as tiny particles in constant, random motion that collide elastically and exert no force between collisions.
In practice
Between collisions, a modeled particle travels a straight line, unaffected by any other particle until it strikes one.
Where people slip
This model explains why the gas laws hold, not a separate topic — its postulates map onto assumptions Chem 1246 already named.
