Gases (page 87) 1.No definite shape or volume, fill container 2.Particles move rapidly in all directions 3.Are fluids 4.Molecules in constant motion, often collide 5.Very low density 6.Are compressible 7.Mostly empty space, spread out easily and mix with one another

Gas Laws (page 88-90) Laws describe how the behavior of gases are affected by pressure and temperature Boyle’s law: relates pressure to volume Charles’s law: relates temperature to volume Gay-Lussac’s law:relates pressure to temperature
5
Boyle’s Law For a fixed amount of gas at a constant temperature: ↓ pressure = ↑ volume P 1 V 1 = P 2 V 2
6
Charles’s Law For a fixed amount of gas at a constant pressure: ↑ temperature = ↑ volume
7
Gay-Lussac’s Law The pressure of a gas at a constant volume is directly proportional to the absolute temperature ↑ temperature = ↑ pressure
