1
Q
Changes of state:
1. Liquid to solid
2. Solid to liquid
3. Liquid to gaseous
4. Gaseous to liquid
A
- Freezing (Release heat)
- Melting (Absorb heat)
- Evaporating/Evaporation, Boiling (Absorb heat)
- Condensing/Condensation (Release heat)
2
Q
Evaporating/Evaporation
A
Changes of state from liquid to gas that can happen at any temperature.
3
Q
Boiling point
A
Temperature that a substance boils
4
Q
High boiling point
A
Particles hold together strongly
5
Q
Low boiling point
A
Particles hold together weakly
6
Q
Condensing/Condensation
A
Change of state from gas to liquid at any temperature below its boiling point
7
Q
How do evaporating particles leave the liquid?
A
Particles leave the liquid surface.
8
Q
How do boiling particles leave the liquid?
A
Bubbles of the substance in the gas state form everywhere in the liquid ; The bubbles rise up to the surface and escape
