Kinetic Molecular Theory
Kinetic Molecular Theory is a set of basic assumptions about gas particles that allows us to predict their behavior fairly accurately. These are the four tenets of Kinetic Molecular Theory (KMT):
- The particles in a gas are small and very far apart. Most of a gas’s volume is empty space.
- Gas particles move in straight lines, in constant random motion. As a result, particles collide with each other and with the walls of the container.
- Collisions between particles are perfectly elastic. No kinetic energy is lost.
- Gas particles do not attract or repel one another.
