Kinetic Theory

  • The theory states that all matter is made of moving particles
  • The particles are always in random motion
  • This means that in every state, particle are always moving
  • Scientist have not yet slowed particles enough to stop them completely

Phases of Matter: Solid, Liquid, Gas

  • Solids keep there shape when put into a container.
  • Molecules in a liquid are close together but swiftly move around each other
  • Gas has no definite volume or shape and takes the shape of the container it's held in
  • Molecules in a gas move very quickly, in random motion, freely around each other, there is a lot of space in between them.

Boyle’s Law, Charles’s Law, Endo and Exothermic Reactions, and Heat of Fusion.

  • Boyle's Law states the relationship between pressure and volume (Higher pressure = lower volume).
  • Charles's Law states the relationship between temperature and volume (High temp = higher volume).
  • Endothermic reactions happen when a substance absorbs energy. Endothermic is when a substance releases energy.
  • Heat of Fusion s the measure of energy needed to melt a solid at its melting point.

Phase Changes

There are 6 different phase changes which are endo and exothermic

  • Solid to a Liquid: Melting-Endothermic
  • Liquid to a Gas: Vaporization-Endothermic
  • Solid to a Gas: Sublimation- Endothermic
  • Gas to a Liquid: Condensation-Exothermic
  • Liquid to a Solid: Freezing-Exothermic
  • Gas to a solid: Deposition-Exothermic
