States of Matter

Melinda drew an illustration of the three states of matter. The illustration below shows what she drew. Melinda wanted to replace the numbers with labels identifying the correct state of matter. How should she change the numbers?

• 1 --> solid; 2 --> liquid; 3 --> gas

• 1 --> gas; 2 --> liquid; 3 --> solid

• 1 --> liquid; 2 --> solid; 3 --> gas

• 1 --> liquid; 2 --> gas; 3 --> solid

Jessica did an investigation about the states of matter. As part of the investigation, Jessica wanted to change a liquid into a solid. What must she do to bring about this change in state?

• Place the liquid in a different container

• Stir the liquid as quickly and thoroughly as possible

• Increase the energy of the liquid so that its particles move faster

• Remove energy from the liquid so that its particles slow down

Solid, liquid, and gas are three states of matter. Which of the following correctly pairs a state of matter and its description?

• gas – particles that do not move about freely

• liquid –particles that are the closest together of all three states

• solid – vibrating particles that are fixed in place

• gas – slowest-moving particles of all three states

The state of matter is an example of a physical property. Why is the state of matter considered a physical property even though a substance may change between a solid, liquid, and gas?

• The property can be easily observed

• The chemical nature of the substance does not change

• The state of matter depends on the amount of substance present.

• Solids, liquids, and gases have different chemical compositions from one another.
