Cycles in matter and water (still in progress!)
Matter:
- Anything that has mass and contains space
- 3 states: solid, liquid and gass
- Solid: Definite shape, definite volume, cannot be compressed
- Liquid: Indefinite shape, definite volume, cannot be compressed
- Gas: Indefinite all
- Solid → liquid (melting)
- Liquid → gas (evaporation/boiling)
- Gas → liquid (condensation)
- Liquid → solid (freezing)
