Vocabulary• Compression: the decrease of gas

volume as a result of applied force• Contraction: the decrease of volume

due to decreased kinetic energy• Expansion: the increase of volume

due to increased kinetic energy• Kinetic energy: the energy of motion

Can a liquid be compres

sed?

We’ve got 3 minutes to burn . . .

•How was the behavior of the water in the syringe different from the behavior of the air in the syringe?•Why do you think water can’t

be compressed?

Now we’ve got 5 minutes. . .

• What happened to the volume of air and the solid sphere when we heated them?

• What caused them to expand? Be detailed?

• What happened to the volume of air and the ring when they were placed in the cold water? Why?

• What happened when you placed your bottle system in cold water? Why?

• If I turn the bottle upside down?• If I surround the

bottle with a hot cloth while upside down?• Why?

What will happen?

Why does water expand?

• Water is made of water particles that are very close together and always moving over and around one another• When the kinetic energy increases (as a

result of added heat), the space between the particles increases• Increased space between particles

results in an increased volume
