States of Matter - SC.8.P.8.1

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

Atoms and molecules are constantly in motion. The more energy the atom or molecule contains, the faster they move about. In which state of matter do the atoms and molecules have the most energy?

• in a liquid
• in a solid
• in a gas
• in both a liquid and a solid

• Jar A contains a gas.
• Jar B contains a liquid.
• Jars A and C have particles that move more than those in Jar B.

Ida made the following table to show the differences between solids, liquids, and gases. Unfortunately, Ida made one mistake. What should be changed so that all the descriptions are accurate?

• liquid – shape definite
• gas – shape varies
• solid – volume varies
• liquid – volume varies

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

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?

• Stir the liquid as quickly and thoroughly as possible.
• Increase the energy of the liquid so that its particles move faster.
• Place the liquid in a different container.
• Remove energy from the liquid so that its particles slow down.

The illustration below shows a molecular model of solid silver, (Ag). The Ag+ particles are silver ions, and the small gray particles are electrons. How would this model change if the solid silver metal were heated?

• The individual Ag+ particles would increase in number.
• The particles would not move.
• The smaller, darker particles would disappear.
• The individual Ag+ particles would move farther apart.

At room temperature, mercury metal exists as a liquid. In contrast, silver metal exists as a solid. Imagine that you had a sample of silver and a sample of mercury, both at room temperature. What can you predict about the two samples?

• Mercury atoms have more kinetic energy than the silver atoms.
• Both silver atoms and mercury atoms do not move from one location to another but simply vibrate while remaining in position.
• Both silver atoms and mercury atoms move fast enough to overcome almost all the attractive forces between them.
• Silver atoms move more freely about compared to the movement of the mercury atoms.

Solids have a definite shape. Solids also have a definite volume. Which statement best explain why solids have both a definite shape and volume?

• The particles of a solid move fast enough to overcome some of the attractive force between them.
• The particles in a solid move fast enough to overcome almost all of the attractive forces between them.
• The particles of a solid remain in fixed positions and are very close together.
• The particles of a solid have very weak attractive forces between them.
