Today we started learning about the behavior of gases and the factors that affect them. Gases are lightweight fast moving particles that generally have a lot of empty space between them. Because of this, they are easily compressible (pictured left). If not contained, gases can spread (or diffuse) to fill any size and shape container.
Gases are affected by pressure, volume, number of moles, and temperature. Changing any one of these variables, changes all the others.
Today we also learned the formula for the Law of Partial Pressure. Basically partial pressures add up to form total pressure. If the total pressure is given then you subtract the partial pressures.
We are still working on moles and making sure we have stoichiometry down pat.
