*NEED HELP ASAP* The diagram shows changes of state between the solid liquid and gas. The atoms of a substate 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?
A-L
B-Μ
C-N
D-O

A-L

Explanation:

Since before the change, the substance is described as having atoms "close together" and "cannot slide past one another", one can assume this is a solid, since in both liquids and gases, the atoms can move around more or less freely.

Then, it explains that the new substance "can fill a container", which is a property of both a liquid and a gas.

Thus, the answer would be either P, solid to liquid, or L, solid to gas.

Since P is not an option you can choose, by process of elimination, that leaves L, or option A.

Have a nice day! ^-^
