States of Matter Multiple Choice Questions and Answers

11. By which process do gases take the shape of their container?

1. evaporation
2. expansion
3. adhesion
4. diffusion

12. During the process of freezing, a liquid

1. loses kinetic energy.
2. loses potential energy.
3. gains potential energy.
4. gains kinetic energy.

13. Food coloring spreads out faster in hot water than in cold water. This is mainly because:

1. The water molecules in hot water move more quickly
2. The molecules in hot water are larger
3. The food coloring molecules are small
4. Hot water is less dense

14. If the rate of evaporation from the surface of a liquid exceeds the rate of condensation,

1. the system is in equilibrium.
2. the liquid is boiling.
3. energy as heat is no longer available.
4. the concentration of the vapor is increasing.

15. If you put food coloring in room temperature water, the coloring spreads throughout the water. The water causes the color to spread mainly because:

1. Water molecules are warm
2. Water molecules are in motion
3. Water is more dense than food coloring
4. Food coloring molecules are small

1. do not move.
2. vibrate about fixed positions.
3. move about freely.
4. exchange positions easily.

17. The compressibility of solids is generally

1. lower than the compressibility of liquids and gases.
2. higher than the compressibility of liquids only.
3. about equal to the compressibility of liquids and gases.
4. higher than the compressibility of gases only.

18. The particles in a liquid are usually

1. closer together and lower in energy than those in a solid.
2. farther apart and higher in energy than those in a gas.
3. closer together and lower in energy than those in a gas.
4. farther apart and lower in energy than those in a solid.

19. To describe a gas, which is incorrect statement:

1. The particles are very attracted to each other
2. The particles are not very attracted to each other
3. The particles of a gas are further apart than the particles in a liquid or solid
4. All of the above

20. To describe a liquid, you could say:
