Multiple Choice

How is the volume of gases different than solids and liquids?

• Gases have a fixed volume like solids.
• Gases cannot expand to fill a container.
• Gases are denser than solids and liquids.
• Gases differ from solids and liquids in that they have no fixed volume and can expand to fill any container.

As temperature decreases, atoms and molecules move ______, decreasing their kinetic energy. (6 letter word)

Multiple Select

What is the relationship between temperature change and the balloon inflating? (multiple correct answers)

• Temperature has no effect on the balloon's size or shape.
• Higher temperatures cause the balloon to inflate due to increased air pressure.
• Lower temperatures cause the balloon to deflate due to decreased air pressure.
• Higher temperatures cause the balloon to shrink due to reduced air pressure.

Multiple Choice

What happens to the kinetic energy of molecules as the temperature increases?

• It decreases

• It remains the same

• It increases

• It fluctuates
