States of Water
States of Water
Water can exist in three forms: as a solid (ice), a liquid (water), and a gas (water vapor or steam).
Melting
Melting
The process where a solid (ice) transforms into a liquid (water) by absorbing heat energy. This occurs at 0°C (32°F), also known as the melting point.
Boiling
Boiling
The process where a liquid (water) changes into a gas (steam) by absorbing heat energy. This occurs at 100°C (212°F), also known as the boiling point.

Study Notes
Water States and Changes
- Water exists in three physical states: solid (ice), liquid (water), and gas (water vapor/steam).
State Changes Table
- Melting: Solid (ice) changes to liquid (water) at 0°C (melting point). Energy is absorbed.
- Boiling: Liquid (water) changes to gas (steam) at 100°C (boiling point). Energy is absorbed.
- Evaporation: Liquid (water) changes to gas (water vapor) at temperatures below the boiling point. Energy is absorbed.
- Freezing: Liquid (water) changes to solid (ice) at 0°C (freezing point). Energy is released.
- Condensation: Gas (water vapor/steam) changes to liquid (water) at or below the boiling point. Energy is released.
