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. A diagram has a triangle at center with gas on top, liquid on bottom right, solid on bottom left. An arrow from gas to liquid is labeled O, and an arrow from liquid to gas is labeled N. An arrow from solid to liquid is labeled P, and an arrow from liquid to solid is labeled Q. An arrow from solid to gas is labeled L, and an arrow from gas to solid is labeled M.
Which arrow represents the change of state described above?

L
M
N
O

L, solid to gas

Explanation:

Both gas and liquid have atoms that can slide past each other, where as, solids have atoms that vibrate in place. The paragraph states that, "Before the change, the atoms are close together and cannot slide past one another.." meaning that the atoms in the substance will be able to slide past each other after the change, and that the substance was a solid before the change. Look back in that text again and you'll find that it also says, "After the change, the substance can fill its container.." meaning that the substance can move freely within its containment system, and that the substance is gas. There was energy added to the electrons in this substance.. there are a few ways of doing that, but the process in which this situation does it is called "sublimation." Sublimation is a phase change where a solid has energy added to it and skips straight into the gas phase with no liquid phase in between. The arrow in the diagram labelled "L" is pointing from solid to gas, making this the answer.
