  1. Henry's Law
  2. Dalton's Law (words)
  3. Molarity
  4. Graham's Law (formula)
  5. Boyle's Law (formula)
  1. a
  2. b The total pressure exerted by the mixture of non-reactive gases is equal to the sum of the partial pressures of individual gases.
  3. c
  4. d moles solute / liters solution; a unit of concentration
  5. e
    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 Multiple choice questions

  1. Constant volume
  2. synonymous with mm Hg

5 True/False questions

  1. Isothermal
    The curved lines on a PV-graph (are called...?)


  2. DiffusionWhen 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. FluidA fluid is a substance that continually deforms (flows) under an applied shear stress. Fluids are a subset of the phases of matter and include liquids, gases, plasmas and, to some extent, plastic solids.


  4. 760 mm Hg ( = ? atm)The average distance traveled by an individual gas molecule before it collides with another gas molecule.


  5. Combined Gas Law
