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



Answer :

Let's analyze the information given in the table and compare it with our knowledge of thermodynamics and phase changes.

1. Melting (solid to liquid): During this process, a substance gains energy (endothermic process) as it absorbs heat to break the bonds in the solid structure.
- Energy Change: Gain

2. Freezing (liquid to solid): This is the reverse of melting. During freezing, a substance loses energy (exothermic process) as it releases heat to form a solid structure.
- Energy Change: Lose

3. Deposition (gas to solid): This is the process where gas changes directly to a solid without passing through the liquid phase. During deposition, a substance loses energy (exothermic process) as it releases heat to form solid particles directly from a gas.
- Energy Change: Lose

4. Condensation (gas to liquid): In condensation, a gas changes to a liquid. During this process, a substance loses energy (exothermic process) as it releases heat to form the liquid from the gas.
- Energy Change: Lose

Given these analyses, let's compare them to the entries in Brian's table:

| Change of State | Energy Change |
|-----------------|---------------|
| Melting | Gain |
| Freezing | Lose |
| Deposition | Gain |
| Condensation | Lose |

From this comparison, we observe that there is an incorrect energy change listed:

- Deposition should have an energy change of "Lose" instead of "Gain".

Thus, the process with the wrong energy change listed is deposition.

So, the correct answer is:
- Deposition
