2.2.3 — Melting, boiling and evaporation

Core

• 2.2.3.1 — Describe melting and boiling in terms of energy input without a change in temperature
• 2.2.3.2 — Know the melting and boiling temperatures for water at standard atmospheric pressure
• 2.2.3.3 — Describe condensation and solidification in terms of particles
• 2.2.3.4 — Describe evaporation in terms of escape of more energetic particles
• 2.2.3.5 — Know that evaporation causes cooling

Supplement

• 2.2.3.6 — Describe differences between boiling and evaporation
• 2.2.3.7 — Describe how temperature, surface area and air movement affect evaporation
• 2.2.3.8 — Explain cooling of an object in contact with an evaporating liquid
