  1. Mean Free Path
  2. R
  3. Graham's Law (formula)
  4. Gay-Lussac's Law (formula)
  5. R-value when dealing with PRESSURE/VOLUME
  1. a .0821 L∙atm/(mol∙K)
  2. b
  3. c universal gas constant
    (a.k.a. molar gas constant, a.k.a. ideal gas constant)
  4. d
  5. e The average distance traveled by an individual gas molecule before it collides with another gas molecule.

5 Multiple choice questions

  1. When there is a barrier with one or many small holes that prevent a gas to expand into the new volume unless a gas molecule happens to travel through the hole. The term "small" when referring to the holes are holes with diameters less than the mean free path of the gas molecules.
  2. synonymous with mm Hg
  3. Constant pressure

  4. where p is the partial pressure of the solute in the gas above the solution, c is the concentration of the solute and k sub-H is a constant with the dimensions of pressure divided by concentration. The constant, known as the Henry's law constant, depends on the solute, the solvent and the temperature.

5 True/False questions

  1. DiffusionIn Chemistry, the term diffusion is defined as the movement of particles of a fluid from a place of relatively high concentration to a place with low concentration. It occurs due to the randomness of motion caused by thermal energy.

          

  2. FluidWhen there is a barrier with one or many small holes that prevent a gas to expand into the new volume unless a gas molecule happens to travel through the hole. The term "small" when referring to the holes are holes with diameters less than the mean free path of the gas molecules.

          

  3. Mole FractionThe number of moles of a component of a solution divided by the total number of moles of all components.
