Unit 3A Review

Susie conducted an experiment in her science class. She placed a balloon filled with air in a beaker of boiling water. After 3 minutes, she removed the balloon from the boiling water and immediately put it into an ice water bath.

What did Susie most likely observe happen to the balloon when she put it in the ice water bath?

• The balloon decreased in size because volume decreases as temperature decreases.

• The balloon decreased in size because volume increases as temperature decreases.

• The balloon increased in size because volume increases as temperature decreases.

• The balloon increased in size because volume decreases as temperature decreases.

A balloon is filled with helium and released. The pressure decreases as the balloon rises. Which will most likely happen to the balloon as it rises?

• The balloon will expand as it rises since the volume will increase.

• The balloon will shrink as it rises since the volume will decrease.

• The balloon will leak gas as it rises and the volume will decrease.

• The balloon will not change as it rises because the volume is constant.

How do the atoms of a solid move?

• Atoms in a solid only shake back and forth in place.

• Atoms in a solid move freely and quickly.

• Atoms in a solid move the same as in a liquid.

• Atoms in a solid do not move.
