Understanding Phase Changes: Liquid to Gas

• When molecules throughout the liquid gain enough energy to enter the gaseous state
• When molecules at the surface of a liquid gain enough energy to enter the gaseous state (correct)
• When molecules within a gas lose enough energy to become liquid
• When molecules within a solid lose enough energy to become liquid

• Only molecules at the surface gain enough energy to enter the gaseous state
• The liquid reaches its freezing point
• The liquid decreases in temperature until it turns into a gas
• Molecules throughout the liquid gain enough energy to enter the gaseous state (correct)

• No, evaporation can occur at any temperature (correct)
• Yes, evaporation only happens at very high temperatures
• Evaporation only happens during certain months of the year
• Evaporation only occurs in extremely cold conditions
