Question

ella makes this table to organize her notes on whether atoms gain or lose energy during the changes of state.

gain energy	lose energy

which changes of state should she place in the column titled \lose energy\?

• freezing, boiling, and melting
• melting, vaporization, and sublimation
• sublimation, deposition, and condensation
• freezing, deposition, and condensation

Explanation:

When a substance changes to a more ordered state (from gas to liquid/solid, liquid to solid), its atoms lose energy:

• Freezing: Liquid → solid (atoms lose energy)
• Deposition: Gas → solid (atoms lose energy)
• Condensation: Gas → liquid (atoms lose energy)

Other processes like boiling, melting, vaporization, and sublimation involve atoms gaining energy as they move to a less ordered state.

Answer:

freezing, deposition, and condensation
