Answer :
Let's carefully examine the changes of state listed in Brian's table along with the corresponding energy changes. Here's what we know about energy changes associated with each state transition:
1. Melting: When a substance changes from a solid to a liquid, it gains energy. The particles need energy to break free from their fixed positions in a solid to move more freely as a liquid. Thus, the energy change should be a gain of energy.
2. Freezing: When a substance changes from a liquid to a solid, it loses energy. The particles release energy as they come together to form a more ordered structure. Thus, the energy change should be a loss of energy.
3. Deposition: This is the process where a gas changes directly into a solid. During deposition, the substance loses energy as it moves into a more ordered, lower-energy state. Thus, the energy change should be a loss of energy.
4. Condensation: This is the process where a gas changes into a liquid. In this process, the substance loses energy as the particles come closer together and move into a more ordered state. Thus, the energy change should be a loss of energy.
Now, let's compare this understanding with the table Brian made:
[tex]\[ \begin{array}{|l|l|} \hline \text{Change of State} & \text{Energy Change} \\ \hline \text{melting} & \text{gain} \\ \hline \text{freezing} & \text{lose} \\ \hline \text{deposition} & \text{gain} \\ \hline \text{condensation} & \text{lose} \\ \hline \end{array} \][/tex]
Comparing each entry:
- Melting: gain (correctly listed)
- Freezing: lose (correctly listed)
- Deposition: gain (incorrectly listed — should be lose)
- Condensation: lose (correctly listed)
The change of state that has the wrong energy change listed is deposition. Therefore, the change of state with the incorrect energy change is:
deposition
