Question

The diagram shows changes of state between solid, liquid, and gas. The atoms of a substance gain energy during a change of state. Before the change, the atoms are close together and cannot slide past one another. After the change, the substance can fill its container.
Which arrow represents the change of state described above?
L
M
N
O

please answer asap! first correct answer gets brainliest!!!

Answer 1

Answer:

L

Explanation:

The details tell us that the substance starts out and its atoms are "close together and cannot slide past one another." This describes a solid: liquids and gases' atoms can move freely, but solids' atoms cannot move. So we know that the substance starts as a solid.

That means the answer must be L or P, because the solid needs to change into something else.

Then the substance gains energy and it can fill its container. Well, this could be either gas or liquid! So it's a good thing that only L is an answer choice, because that means L is correct and the change is from solid -> gas.
