Matter Test Review

How does the temperature of a substance relate to its density?

• A warmer substance will be less dense, because the atoms are expanding.

• A warmer substance will be more dense, because the atoms are contracting.

• A cooler substance will be less dense, because the atoms are expanding.

• There is no relationship between the temperature and density of a substance.

Scientists are observing molecules by using an advanced electron microscope. They notice the molecules are beginning to move faster and expanding. What is most likely happening?

• Heat is being added, and a gas is turning into a liquid.

• Heat is being added, and a solid is turning into a liquid.

• Heat is being removed, and a gas is turning into a solid.

• Heat is being removed, and a liquid is turning into a solid.

How are the temperature of a substance and the movement of atoms in a substance related?

• When the temperature increases, the movement of atoms decreases.

• When the temperature decreases, the movement of atoms increases.

• When the temperature decreases, the movement of atoms decreases.

• When the temperature decreases, the movement of atoms is unchanged.

A helium balloon is taken outside on a very cold day. The balloon wrinkles and becomes a little smaller. Why does the balloon deflate when it exposed to the cold air?

• The colder temperature causes the gas in the balloon to expand because the particles are moving farther apart.

• The colder temperature causes the gas in the balloon to contract because the particles are moving closer together.

• The colder temperature causes the gas in the balloon to escape.

• The colder temperature causes more gas to enter the balloon, and it expands.

Which statement best explains the relationship between temperature and the kinetic energy of atoms?

• As temperature increases, the kinetic energy increases.

• As temperature decreases, the kinetic energy increases.

• As temperature increases, the kinetic energy converts into potential energy.

• As temperature decreases, the kinetic energy converts into potential energy.

The diagram compares the movement of water particles when the water is cold compared to when it is hot.

What happens to the particles in the cold water?

• The particles in the cold water contract and move more slowly

• The particles in the cold water expand move more quickly.

• The particles in the cold water move more freely.

• The particles in the cold water do not move at all.

What will most likely occur if water is cooled until it becomes solid ice?

• The particles of water will speed up and expand.

• The particles of water will slow down and contract.

• The particles of water will not change speed.

• The particles of water will stop moving completely.
