1. Three Common States of Matter
3.1
Matter is made of tiny particles called atoms or molecules that are in a constant state of motion. The type of motion determines the state of matter

2. Solid Has definite shape and volume
Particles of matter are very close together and have a strong attraction for one another which locks them in place.
Particles vibrate in place.
Two types:
Crystalline –Solid which has an orderly three dimensional arrangement of particles including a repeating pattern of rows. Ex: iron
Amorphous- particles do not have a specific pattern of arrangement. Ex: rubber, glass & wax.

3. Liquid
Has a definite, measurable volume but takes the shape of its container
Faster particle movement than in solids allows particles to change position
Particles slip past one another until liquid takes the shape of the container.
Surface tension is a force that acts on the surface of a liquid that can cause them to form spherical drops.
Viscosity is the resistance to flow. The stronger the attraction between particles, the higher the viscosity.

4. Gas
Has no definite shape or volume. It expands to fill and take the shape of its container.
Particle movement is fast enough so that particles can break away from each other and move independently
Can be compressed.
