Kinetic Theory of Matter Quiz

Study Notes

States of Matter

Matter exists in three main states: solid, liquid, and gas.
Each state has distinct properties and particle behavior.

Particle Behavior

In a solid, particles are closely packed, vibrate in place, and have a fixed shape and volume.
In a liquid, particles are close together, can slide past each other, and have a fixed volume but take the shape of their container.
In a gas, particles are widely spaced, move freely, and have neither a fixed shape nor volume.

Changes of State

Melting: a solid changes to a liquid when heated, particles gain energy and start moving more freely.
Solidification: a liquid changes to a solid when cooled, particles lose energy and start moving closer together.
Boiling: a liquid changes to a gas when heated, particles gain energy and start moving rapidly.
Condensation: a gas changes to a liquid when cooled, particles lose energy and start moving closer together.
Sublimation: a solid changes directly to a gas or a gas changes directly to a solid without going through the liquid phase, occurs when particles have enough energy to overcome intermolecular forces.

Kinetic Theory

Explains the behavior of particles in different states of matter and during changes of state.
Based on the idea that particles are in constant motion, and their velocity and energy increase with temperature.

Description
