phase changes
Melting- indicates a change from a solid to a liquid. ( melting point )
Freezing- Changing from a liquid to a solid. ( freezing point )
(Melting and freezing occur at the same temperature)
Liquification- Turning a gas into a liquid.
Boiling- used to indicate changing from a liquid to a gas/ vapor. ( boiling point )
- Two Types-
Condensation- used to indicate changing from a vapor to a liquid. ( condensing point)
Sublimination- when a substance changes directly form a solid to a vapor.
Deposition- when a substance changes directly from a vapor to a solid ( opposite of sublimation)
Dynamic equilibrium- when a vapor is in equilibrium with it's liquid as one molecule leaves the liquid to become a vapor, another molecule leaves the vapor to become a liquid.
Difference in gas and vapor
Freezing- Changing from a liquid to a solid. ( freezing point )
(Melting and freezing occur at the same temperature)
Liquification- Turning a gas into a liquid.
Boiling- used to indicate changing from a liquid to a gas/ vapor. ( boiling point )
- Two Types-
- evaporation takes place only at the surface of a liquid or solid
- boiling takes place throughout the body of a liquid.
Condensation- used to indicate changing from a vapor to a liquid. ( condensing point)
Sublimination- when a substance changes directly form a solid to a vapor.
Deposition- when a substance changes directly from a vapor to a solid ( opposite of sublimation)
Dynamic equilibrium- when a vapor is in equilibrium with it's liquid as one molecule leaves the liquid to become a vapor, another molecule leaves the vapor to become a liquid.
Difference in gas and vapor
- Gas-state of matter that exists at normal room temp.
- Vapor-produced by particles escaping from a state of matter that is normally liquid or solid at room temp.
T = the triple point this is where all three lines connect
C= the critical point
