Question

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

Answer 1

Answer:

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

Explanation:

The best phrase that compares matter to their phases is that a solid is like the tray being shaken slowly with the marbles moving in their position(fixed), the liquid is like the tray being shaken and the marbles moving around it (flow) and the gas is like the tray being shaken hard and the marbles moving vigorously around it.

• The particles of matter are in a continual motion.
• This suggests that they possess kinetic energy.
• In gases the molecules are random and moves very fast. It is similar toe the tray being shaken and the marbles moving vigorously.
• In liquids the molecules flow and move less randomly.
• Solids vibrates about their fixed lattice points.

Answer 2

The different phases of the matter can be compared to the marbles in the tray in the following ways:

If the marbles in the tray are tightly packed and do not move around, it becomes a model for the motion of atoms in solids.

• In solids, there is no intermolecular space, and the molecules are tightly packed with each other. Hence solids have definite shapes.

If the marbles move partially on the tray, it is a model of atomic motion in liquid. The marbles do not get free reign to move, but they are not tightly packed like solids.

• Liquids have more intermolecular space than solids and can move around slightly. Therefore fluids flow and take the shape of the container in which we keep them.

If the marbles can move from one corner of the tray to the other, it is a model of atomic motion in gases.

• Gases have the largest intermolecular spaces. Therefore, they can freely move from one place to another and has no particular shape.
