Sagot :
Let's analyze the energy changes that correspond to various changes of state:
1. Melting: This is the process where a solid turns into a liquid. Typically, when a substance melts, it absorbs heat from its surroundings, leading to a gain of energy.
2. Freezing: This is the process where a liquid turns into a solid. In this process, the substance releases heat to its surroundings, resulting in a loss of energy.
3. Deposition: Deposition is the process where a gas turns directly into a solid without passing through the liquid state. This process involves the gas releasing heat as it changes state, causing a loss of energy.
4. Condensation: This is the process where a gas turns into a liquid. During condensation, the gas releases heat to the surroundings, resulting in a loss of energy.
Given Brian's table:
[tex]\[ \begin{tabular}{|l|l|} \hline \multicolumn{1}{|c|}{ Change of State } & \multicolumn{1}{c|}{ Energy Change } \\ \hline melting & gain \\ \hline freezing & lose \\ \hline deposition & gain \\ \hline condensation & lose \\ \hline \end{tabular} \][/tex]
We can see that:
- The energy changes listed for melting and freezing are correct.
- The energy change listed for condensation is correct.
However, for deposition, the correct energy change should be a loss of energy, not a gain of energy as listed in Brian's table. Therefore, the change of state that has the wrong energy change listed is:
deposition.
