Brian made this table to organize his notes on changes of state:

\begin{tabular}{|l|l|}
\hline \multicolumn{1}{|c|}{Change of State} & \multicolumn{1}{c|}{Energy Change} \\
\hline melting & gain \\
\hline freezing & lose \\
\hline deposition & gain \\
\hline condensation & lose \\
\hline
\end{tabular}

Which change of state has the wrong energy change listed?

A. condensation
B. deposition
C. melting
D. freezing

Let's analyze the energy changes associated with different changes of state in matter:

1. Melting: This is the process in which a solid turns into a liquid. For this to happen, the substance must absorb energy to break the bonds holding the molecules in a solid structure. Therefore, melting requires gaining energy.

2. Freezing: This process is the opposite of melting. A liquid turns into a solid, and during this process, energy is released as the molecules form bonds and settle into a solid structure. Hence, freezing requires losing energy.

3. Deposition: This is the process where a gas directly turns into a solid without passing through the liquid state. For a gas to become a solid, it must release a significant amount of energy to allow the molecules to form a solid structure. Therefore, deposition requires losing energy.

4. Condensation: This is the process where a gas turns into a liquid. Energy is released when molecules in a gas state come together to form a liquid. Thus, condensation requires losing energy.

Comparing these descriptions with the table provided:

- Melting is correctly listed as gaining energy.
- Freezing is correctly listed as losing energy.
- Condensation is correctly listed as losing energy.

However, deposition is incorrectly listed in the table as gaining energy, when in fact, it should be described as losing energy.

Therefore, the change of state with the wrong energy change listed is:
deposition.
