# State of Matter and Their Changes Study Guide

```State of Matter and Their Changes Study Guide
1. The four states of matter are: solid, liquid, gas, and plasma
2. Understand the characteristics of a solid, liquid and gas.

3. The states of matter are based on three things:
a. Particle arrangement
b. Energy of particles
c. Distance between particles
4. Matter is made up of particles which are in continual random motion.
5. If you add heat to matter, the atoms that make up the matter will begin to
move faster.
6. If you remove heat from matter, the atoms that make up the matter will
begin to move slower.

10. Matter is everything that has mass and volume.
11. The temperature at which a solid turns into a liquid is the melting point.
12. The temperature at which a liquid turns into a gas is the boiling point.
13. Viscosity is resistance of a liquid to flow.
14. Know what surface tension is and give an example.
15. Amorphous solids have no orderly arrangement of particles
16. Crystalline solids have an orderly arrangement of particles.
