  4. R-value when dealing with ENERGY
  5. R
  1. a In 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. b universal gas constant
    (a.k.a. molar gas constant, a.k.a. ideal gas constant)
  3. c
  4. d 8.31 J/(mol∙K)
  5. e Constant pressure

5 Multiple choice questions

  1. The average distance traveled by an individual gas molecule before it collides with another gas molecule.
  2. Constant volume

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

  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. .0821 L∙atm/(mol∙K)
