Question

brian made this table to organize his notes on changes of state.

change of state	energy change
freezing	lose
deposition	gain
condensation	lose

which change of state has the wrong energy change listed?

• condensation
• deposition
• melting
• freezing

Explanation:

To determine the wrong energy change, recall:

• Melting: Solid → Liquid (needs energy, gain ✔️).
• Freezing: Liquid → Solid (releases energy, lose ✔️).
• Deposition: Gas → Solid (releases energy, should lose energy, but listed as gain ❌).
• Condensation: Gas → Liquid (releases energy, lose ✔️).

Deposition (gas to solid) is an exothermic process (loses energy), but the table says "gain".

Answer:

B. deposition
