An inflated balloon is placed in a refrigerator. Which statement describes the movement of the gas particles in the balloon?

• The particles move more slowly and become closer together.
• The particles move more slowly and become further apart.
• The particles move faster and become closer together.
• The particles move faster and become further apart. 

In which segment is the kinetic energy remaining constant?

• A-B
• B-C
• C-D
• E-F

What line segment represents only the solid state?

• A-B
• B-C
• C-D
• D-E

Between which points is water changing states of matter?

• A <----> B

• B <----> C

• C <----> D

• D <----> E

• E <----> F

The more energy particles have...

• the faster they move.

• the farther apart they tend to be.

• the hotter they are.

• All of the above

Why do particles come closer together when they lose energy?

• ...the attractive forces between the particles pull them back together.

• ...they dissolve.

• ...they become a solid.

• ...they are more attracted to the solvent than the solute.

What would cause a decrease in particle movement?

• decrease atoms
• increase in space between atoms
• decrease in temperature
• increase in mass

Which states of matter exist between points B and C?

• Solid and liquid
• Liquid and gas
• Gas and solid

When something goes from gas to liquid, it is called...

• Evaporation

• Condensation

• Deposition

• Freezing

Which of the following statements about the particle of a gas is true?

• Gases can be compressed because their particles are smaller than those of liquids or solids.
• Gases can be compressed because there is plenty of space between their particles.
• Gases can be compressed because they have low boiling points.
• Gases can be compressed because their particles are more elastic than those of liquids or solids.
