Question

How IS energy related to the change of state represented

by the model?
Atoms gain energy as a solid changes to a gas.
Atoms gain energy as a liquid changes to a gas.
Atoms lose energy as a solid changes to a gas.
Atoms lose energy as a liquid changes to a gas.

Answer 1

The answer is...Liquid into gas.

My Explanation:

Stated in the model, The atoms aren't that active but can still slider past each other; meaning, this is a liquid. As it shifts into a gas, which is when atoms pick up energy and move around more freely/actively, the definition of the following is "Vaporization".

So the answer is: B, or in other words, "Atoms gain energy as a liquid turns into a gas.

Answer 2

Gain energy as a liquid changes to a gas

Step-by-step explanation:

get further apart= more kinetic energy

liquid at beginning as not uniform but quite close together and takes shape of container
