An analogy makes a comparison between objects based on their similar qualities. Cassidy wanted to create an analogy for the moti

on of atoms in solids, liquids, and gases, so she compared them to marbles in a tray. Which best compares the phases of matter to marbles in a tray?
A) A solid is like the tray being shaken and the marbles moving around it, and a liquid is like the tray being shaken slowly and all the marbles moving in their positions.

B) A solid is like the tray being shaken slowly and all the marbles moving in their positions, a liquid is like the tray being shaken and the marbles moving around it, and a gas is like the tray being shaken hard and the marbles moving vigorously around it.
C) A gas is like the tray being shaken slowly and all the marbles moving in their positions, and a solid is like the tray being shaken hard and the marbles moving vigorously around it.
D) A liquid is like the tray being shaken hard and the marbles moving vigorously around it, and a gas is like the tray being shaken slowly and all the marbles moving in their positions.

The correct option is B.

Matters exist in three phases, which are solid, liquids and gas. These three phases behaves differently based on their structures. Solids have definite shape and volume and their particles are tightly connected, so their particles vibrate about a fixed position. Liquids have definite volume but no shape. The inter molecular force among liquid particles is not as strong as that of solid, so the particles can move around slowly. Gases has no shape and no volume. The inter molecular force in gas particles are negligible and thus, they move about freely and randomly and fill all the available spaces.

I think the correct answer from the choices listed above option B. A solid is like the tray being shaken slowly and all the marbles moving in their positions, a liquid is like the tray being shaken and the marbles moving around it, and a gas is like the tray being shaken hard and the marbles moving vigorously around it. Hope this helps.
