Extreme Expansion!
• Why did my bike tire explode when I left it in my car last week?

![Page 25: Physical Science Heat and Matter Review. Within a substance, A: all particles have the same energy B: all particles move at the same rate C: some particles.](https://reader035.fdocuments.in/reader035/viewer/2022062722/56649f305503460f94c4bb22/html5/thumbnails/25.jpg)
Water: the exception to the expansion / contraction rule
• What happens to liquid water as it cools from room temperature to freezing?– The particles in the liquid contract until just
before they freeze. Then they form rings as they freeze, and actually expand!
![Page 26: Physical Science Heat and Matter Review. Within a substance, A: all particles have the same energy B: all particles move at the same rate C: some particles.](https://reader035.fdocuments.in/reader035/viewer/2022062722/56649f305503460f94c4bb22/html5/thumbnails/26.jpg)
Conduction or Convection?
• Ice cube melts in your hand
• Conduction (direct transfer of heat)
• Liquid wax floats then sinks then floats again in a lava lamp
• Convection (transfer of heat by moving particles)

Radiation
• Give some examples of transfer of heat by radiation:
• The sun warms your hand with it’s UV rays

Great Job!
• Study hard for the test, any of these questions, and many others, could appear on it!!!!!!!
