• volume & temperature
• temperature & pressure
• volume & moles (amount of gas)

• direct
• inverse
• linear
• exponential

At constant pressure, what happens to temperature of a gas when the volume doubles?

• The temperature also doubles.
• The temperature decreases to half of its original volume.
• The temperature doesn't change.
• The temperature quadruples.

Which of the following phenomena best illustrates Charles' Law?

• carbon dioxide being dissolved in water
• expansion of the balloon as it is being submerged in hot water
• breathing apparatus being used by a patient
• leavening agent causing the fluffiness of cake products

A balloon is placed inside a freezer causing its temperature to reduce to 50%.  What happened to its volume?

• Its volume is reduced to 50%
• Its volume is reduced to 25%
• Its volume is increased by 50%
• Its volume is increased by 25%
