Study Notes
Freezing
- Freezing is the process of a substance changing from a liquid to a solid state.
- Water freezes at 0°C (32°F) at standard atmospheric pressure.
- Supercooled liquids, like supercooled water, can freeze without being cold to the touch.
- During freezing, the thermal energy of a substance decreases, and the molecules slow down, coming together to form a crystal lattice structure.
- A substance's freezing point is the temperature at which it changes state from a liquid to a solid, and it is a specific temperature that is unique to each substance.
