A Journey Through States of Water
Explore how water shape-shifts between ice, liquid, and vapor!
Solid — Ice ❄️
- Molecules locked in a rigid structure.
- Exists below 0 °C (freezing point).
- Melting changes ice to liquid water.
Why does salt melt ice?
Salt lowers the freezing point of water, so ice absorbs heat and melts even when air temperature is below 0 °C.
Liquid — Water 💧
- Molecules slide past one another freely.
- Exists between 0 °C and 100 °C at sea level.
- Evaporation turns water into vapor.
Why do clothes dry faster in the sun?
Sunlight warms water molecules, giving them the energy to escape into the air (faster evaporation).
Gas — Water Vapor ☁️
- Molecules move wildly and spread apart.
- Forms at 100 °C (boiling point) or below via evaporation.
- Condensation changes vapor back to liquid.
What is sublimation?
Direct transition from solid to gas without becoming liquid (e.g., dry ice).
