Document Summary

Need these to determine everything you need to know about the state of matter. Pressure is important for gases because they exert pressure in all directions. Pressure from atm makes the mercury rise column of mercury is exerting its own pressure will continue to rise until the pressure on the outside matches the pressure on the inside. P = gh; g = gravity, = pressure, h = height. When you increase the energy from 300k to 900k, the distribution heads to the right towards greater kinetic energy. At the peaks, it is the most popular kinetic energy spot for molecules. Regardless of any gas, they will have that kind of distribution at 300 and 900k. The average kinetic energy increases with temperature: ke = Physics definition: ke = mu2; u = velocity (not using v because this measure of speed is not the one that we"re most comfortable with)
