Question

which of the following changes in state require energy to occur? which release energy? sort the items into the appropriate bins. view available hint(s) reset help condensation evaporation freezing melting sublimation deposition energy is required energy is released

Explanation:

To determine energy - related state changes:

• Energy is required: These are endothermic processes where a substance absorbs energy to change state.
• Melting: Solid to liquid (needs energy to break intermolecular forces).
• Evaporation: Liquid to gas (needs energy for molecules to escape liquid phase).
• Sublimation: Solid to gas (directly, requires energy to overcome forces in solid).
• Energy is released: These are exothermic processes where a substance gives off energy when changing state.
• Freezing: Liquid to solid (intermolecular forces form, releasing energy).
• Condensation: Gas to liquid (molecules come closer, energy is released).
• Deposition: Gas to solid (directly, energy is released as molecules settle into solid structure).

Answer:

• Energy is required: Melting, Evaporation, Sublimation
• Energy is released: Freezing, Condensation, Deposition
