Heat
is a form of energy
Melting point

Boiling point
Is when a liquid turn to a gas
Freezing point
Is when a liquid turns to a solid
Condensation
Is a gas turning into a liquid
Latent heat
The heat taken in or given out when a substance is changing state without a change in temperature.
Latent heat of fusion
Is used when a solid changes into a liquid
Latent heat of vaporisation
Is used when a liquid changes to a gas
Radiation can
A dull black surface radiates and absorbs heat better than a shiny silver surface
Summary
Lowers the boiling point
Higher pressure
Raises the boiling point
