When you are looking at problems dealing with gases, visualizing a balloon is a good starting point. There are four basic ways to change (or parameters) the balloon. These are: 1.Volume, V, usually has units of Liter, defined as volume occupied by gas particles 2.Temperature, T, degree C or Kelvin (K), can be thought of as "relative speed" of particles. In all gas law calculations, T must be in K **To convert from degree C to K use following equation: degree C + 273 = K 3.Pressure, P, usually in atm, can be thought of as the number of hits on the wall of the container (from all the particles). Others units and their equivalence to atmospheric pressure are: **1.00atm = 760.mmHg = 101.3 kPa = 14.7psi = 33ft H2O = 760. torrs 4.Number of moles of gas particles, n, units of moles |
