Question

The diagram shows changes of state between solid, liquid, and gas. The atoms of a substance lose energy during a change of state. After the change, the atoms are close together but are able to slide past one another. 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 N O P

Answer 1

Arrow 'Q' represents the transition from a liquid to a solid, known as freezing, where atoms lose energy and become closely packed but unable to slide past one another freely.

Step-by-step explanation:

The student is asking about a change of state where atoms lose energy and change from one state to another, with the resultant state having atoms that are close together but able to slide past one another. This description is characteristic of the change from a liquid to a solid, known as freezing.

In the context of the diagram provided with the question, the arrow labeled 'Q' represents the transition from a liquid to a solid. During this process, the liquid loses energy and transitions to the solid phase, where the atoms become closely packed in a fixed arrangement, but unlike in the liquid state, they can no longer move or slide past each other freely.
