1. Properties of Gases…

2. A. Def – how much the volume changes under pressure. 1. Think…Why would you want to hit an airbag instead of a steering wheel or dashboard? a. Gases are compressible…absorb impact B. How are gases compressible? 1. spaces in between particles

3. A. Variables… 1. amount of gas 2. volume 3. temperature B. Amount of gas 1. increase number of particles  pressure goes up (pg. 415)  container could burst… 2. decrease number of particles  pressure goes down

4. C. Volume 1. Increasing volume…  pressure decreases 2. Decreasing volume  pressure increases

5. D. Temperature 1. Temperature increases…  pressure increases 2. Temperature decreases…  pressure decreases
