matter review

1. Which one of the following statements is true about matter?

• Solids have a definite shape and definite volume; particles only vibrate and have only a little bit of kinetic energy.
• Gases have no definite shape, a definite volume; particles move around a little freely and have some kinetic energy.
• Liquids have no definite shape, no definite volume; particles move around very freely and have a lot of kinetic energy.
• Solids, liquids, and gases have a definite shape and a definite volume. Particles move around freely and have a lot of kinetic energy

2. What happens to any state of matter when you add heat/thermal energy to it?

• A. The matter will disappear never to be seen again.
• B. The matter will have a phase change due to the addition of kinetic energy provided by the heat/thermal energy.
• C. The matter will not have a phase change as kinetic energy will be taken away by the heat/thermal energy.
• D. The matter will have a phase change due to losing kinetic energy being taken away by the heat/thermal energy.

3. What causes windshields to be wet and the grass to be wet on some mornings even when it has not rained during the night?

• A. Water seeping up from the ground makes them wet.
• B. Heat/thermal energy is taken away at night when the Sun goes down and water vapor, a gas, turns back into liquid water. This is called evaporation.
• C. Heat/thermal energy is taken away at night when the Sun goes down and water vapor, a gas, turns back into liquid water. This is called condensation.
• D. Heat/thermal energy is added at night when the Sun goes down and water vapor, a gas, turns back into liquid water. This is called condensation.

4. At what phase of matter do the atoms/molecules completely stop moving?

• A. When the matter turns into a gas.
• B. When the matter turns into a solid.
• C. When the matter turns into a liquid.
• D. Atoms/molecules are always moving, even if just vibrating like in solids.

5. Which two forms of matter take the shape of the container they are in?

• A. Liquids and gases
• B. Solids and liquids
• C. Solids and gases
• D. Some liquids and all gases

6. Which of these are the basic states of matter?

• A. Rock, plant, and animal
• B. Water, ice, and air
• C. Solid, liquid, and gas
• D. Hard, soft, and sticky

7. Which of these best describes a solid form of a substance?

• A. The solid has a definite shape and volume.
• B. The solid has the shape of the container that holds it.
• C. The solid has particles with more kinetic energy than particles in gases.
• D. The solid has particles that are farther apart than the particles in liquids.

8. What makes up all types of matter?

• A. Matter is made of hard solid round balls that cannot move.
• B. Matter is made of tiny particles that are too small to be seen.
• C. Matter is made of solid pieces of air or water that are close together.
• D. Matter is made of bits of dust that are tightly packed together.

9. Which of these is a state of matter that has particles with the highest kinetic energy?

• A. A ball
• B. A liquid
• C. A gas
• D. A solid

10. Which of these best shows the particles in a solid?

•
