False
What are the different types of vaporization?
Evaporation and boiling
What is evaporation?
Vaporization but takes place only on the surface of a liquid
What happens to the particles in a liquids freezing point?
The particles move slow that they begin to take on their fixed positions
What is the difference between homogeneous and heterogeneous?
The difference is that homogeneous is a substance that you cannot see the difference is but in heterogeneous you can see the different pieces in the substances.
