Question

match the phase change with its description
sublimation ∘ ∘ solid --> liquid
deposition ∘ ∘ liquid --> gas
melting ∘ ∘ gas --> liquid
boiling ∘ ∘ liquid --> solid
condensation ∘ ∘ gas --> solid
freezing ∘ ∘ solid --> gas

Explanation:

• Sublimation: The process where a solid directly changes to a gas, so Sublimation matches Solid -> Gas.
• Deposition: The reverse of sublimation, where a gas directly changes to a solid, so Deposition matches Gas -> Solid.
• Melting: The process where a solid changes to a liquid, so Melting matches Solid -> Liquid.
• Boiling: The process where a liquid changes to a gas (vaporization at boiling point), so Boiling matches Liquid -> Gas.
• Condensation: The reverse of boiling, where a gas changes to a liquid, so Condensation matches Gas -> Liquid.
• Freezing: The reverse of melting, where a liquid changes to a solid, so Freezing matches Liquid -> Solid.

Answer:

• Sublimation: Solid -> Gas
• Deposition: Gas -> Solid
• Melting: Solid -> Liquid
• Boiling: Liquid -> Gas
• Condensation: Gas -> Liquid
• Freezing: Liquid -> Solid
