To determine which change of state has the wrong energy change listed, let's review the correct energy changes for all the states of matter mentioned.
1. Melting:
- This is the process where a solid turns into a liquid.
- It requires energy to break the bonds holding the solid together.
- Correct energy change: Gain.
2. Freezing:
- This is the process where a liquid turns into a solid.
- Energy is released as the liquid solidifies and forms bonds.
- Correct energy change: Lose.
3. Deposition:
- This is the process where a gas turns directly into a solid without becoming liquid.
- Energy is released during deposition as the gas particles lose energy and form a solid.
- Correct energy change: Lose.
4. Condensation:
- This is the process where a gas turns into a liquid.
- Energy is released as the gas particles come together to form a liquid.
- Correct energy change: Lose.
Reviewing Brian's table:
- Melting: gain (correct)
- Freezing: lose (correct)
- Deposition: gain (incorrect, should be lose)
- Condensation: lose (correct)
The correct energy change for deposition is "lose" rather than "gain".
Therefore, the change of state with the wrong energy change listed in Brian's table is deposition.
