Forms of water Water changes phase due to temperature These are physical changes

Latent heat

Density How much mass is in a certain volume. Density anomaly- as water gets colder the density decreases

Specific heat How much energy is needed to heat up a certain amount of a substance Unique for each substance Water has a high specific heat
