Hello, I'm Jeff. We will be learning about states of matter.
4 States of matter Solid Liquid Gas Plasma
The thing that causes change in phases of matter is energy.
When energy is added, particles within an object will gain kinetic energy, which causes the particles within the object move more. begin to move faster, until they change into the next state, and they will move slower when energy is subtracted.
Melting- Solid to Liquid Vaporization- Liquid to Gas Condensation- Gas to Liquid Freezing- Liquid to Solid Sublimation- Solid to Gas Deposition- Gas to Solid
There are 2 basic types of phase changes. Endothermic, and Exothermic. Exothermic means to release energy to its surroundings, endothermic means to absorb energy from them.
I hope you learned something today!! Stay cool, and Stay in school.
