3.5: Kinetic Molecular Theory

Learning Objectives

• I can explain the relationship between the motion of particles and the macroscopic properties of gases with:

1. The Kinetic Molecular Theory (KMT)

2. A particulate model

3. A graphical representation

kinetic molecular theory (kmt)

Maxwell-boltzmann distribution

what affects the kinetic energy of gases?

Kinetic energy of gases depend on both their masses and the temperature. Gases at higher temperature have higher velocities than gases at low temperature. This means that the higher the temperature of a gas, the faster the gas particles move.
