  1. Isobaric
  2. Henry's Law
  3. Boyle's Law (graph)
  4. R-value when dealing with ENERGY
  5. Graham's Law (words)
  1. a
  2. b
    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.
  3. c 8.31 J/(mol∙K)
  4. d The rate of effusion of a gas is inversely proportional to the square root of the mass of its particles.
  5. e Constant pressure

5 Multiple choice questions

  1. A 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.
  2. moles solute / liters solution; a unit of concentration
  3. The total pressure exerted by the mixture of non-reactive gases is equal to the sum of the partial pressures of individual gases.
  4. 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.

  1. torrsynonymous with mm Hg


  2. 760 mm Hg ( = ? atm)The average distance traveled by an individual gas molecule before it collides with another gas molecule.


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


  4. Boyle's Law (formula)


  5. IsothermsConstant temperature
