An overview of the Kinetic Molecular Theory (KMT) and its application to explain the properties and behavior of matter in its different states: solids, liquids, and gases. The theory explains how particles' motion and collisions contribute to the observable characteristics of these states, as well as the concept of intermolecular forces. Additionally, the document discusses phase changes and their relation to energy.

Identify whether matter is a solid, liquid, or gas based on
Kinetic Molecular Theory (KMT).
MATTER.
Describe what happens to particles of matter as they change
from solid, liquid, and gas.
Solids have a definite shape and volume, and are not compressible. Liquids have a definite volume but not a definite shape. They are not compressible. Gases do not have a definite shape or volume. Gases are compressible.
Intermolecular forces include dipole-dipole interactions, hydrogen bonding, and London forces.
Particles in Solids, Liquids, and Gases
Particles stick together in rigid position.
Particles stick together but can move past each other.
Particles fly rapidly past each other as if there are no attractive forces between them.
Phase changes
