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

A 2-column table with 4 rows. The first column titled change of state has entries melting, freezing, deposition, condensation. The second column labeled energy change has entries gain, lose, gain, lose.

Which change of state has the wrong energy change listed?

condensation
deposition
melting
freezing

1 answer

The change of state with the wrong energy change listed is deposition.

Here’s the correct information:

  • Melting: Gain energy (solid to liquid)
  • Freezing: Lose energy (liquid to solid)
  • Deposition: Lose energy (gas to solid)
  • Condensation: Lose energy (gas to liquid)

In your table, deposition is marked as "gain," which is incorrect; it should be "lose."
