5 Points to the Particle Model of Matter

A
  • All substances are made of tiny particles.
  • All particles in a pure substance are the same, different pure substance are -made of different particles
  • The particles all have space between them
  • The particles are always in motion. The speed of the particles increases when heat is added and decreases when heat is taken away.
  • The particles in a substance are attracted to one another. The strength of the attractive forces depend on the type of particle

Q

Changes of states and What are They?

A
  1. Melting/fusion- the process of changing from a solid to a liquid.
  2. freezing/solidification- The process of changing a liquid to a solid.
  3. Condensation/evaporation- the process of changing from a gas to a liquid.
  4. Vaporization- The process of changing from a liquid to a gas. Note that evaporation is a slowere form of vaporization and boiling is a faster form of vaporization.
  5. Sublimation- The process of going from a solid to a gas or a gas to a solid without going through the liquid state.
    the relationship between solid and gas is always sublimation.
