Phase Change - Coggle Diagram
Phase Change
Requires energy
Vaporization
Occurs only at the surface of the liquid
Two types
Boiling
Evaporation
Liquid to gas
Boiling point
Sublimation
From solid directly to gas
Example: dry ice
Melting
It requires heat
Breaks down intermolecular force (melting point)
Solid to liquid
Releases energy
Condensation
Velocity decreases
Formation of hydrogen bonds release thermal energy
Gas to liquid
Deposition
Solid to gas immediately
Reverse of sublimation
Freezing
Particles lose KE and decrease in velocity
Molecules are less likely to flow past one another
Liquid to solid
