A Journey Through States of Water — Class 6 Science

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).
