Kinetic Molecular Theory

Kinetic Molecular Theory (KMT)

Model used to describe the behavior of gases. Specifically, it explains how macroscopic properties, such as pressure and temperature are related to the behavior of molecules

Basic Assumptions on The Nature of Gas

•Constant, Random motion - moves constantly and randomly

•Neglible particle volume/No definite volume - too small of a volume

•Brownian Motion - moves in a straight line unless collided

•Elastic Collission - no kinetic energy is lost when colliding

•Kinetic energy is proportional to temprature - high heat, high kinetic energy vice verse

Ideal Gas

Follows all assumptions of the KMT. Does not exist, but you can treat real gases as ideal in most situation

Real Gas

Has molecules that occupy space and interact with one another. Unlike Ideal, Real gases cannot be compressed indefinetly
