slide2

These graphs show the electric potential outside a uniformly charged plane (membrane) as a function of distance away from the plane.  Both curves represent measurements of electric field magnitude in an ionic solution, and both represent the same concentration of ions, but they are at different temperatures.  Which of the following explains which curve is which?

  • The blue curve represents a solution at higher temperature.
  • The red curve represents a solution at higher temperature.
  • We can't determine anything about temperature from this graph.  Temperature has no effect on electric field, so there must be some other factor causing the two curves to be different.
  • None of these.

These graphs show the electric potential outside a uniformly charged plane (membrane) as a function of distance away from the plane.  Both curves represent measurements of electric potential in an ionic solution.The graphs represents the electric potential in two solutions at the same temperature, with different concentrations of ions.  Which curve is which?

  • The blue curve represents a solution with greater concentration of ions.
  • The red curve represents a solution with greater concentration of ions.
  • We can't determine anything about the concentration of ions from this graph.
  • None of these.
slide4

These graphs show the electric potential outside two uniformly charged planes (membrane) as a function of distance away from the plane.  Both curves represent measurements of electric potential in an ionic solution.Which curve has the greater Debye length?

  • The solution represented by the blue curve has a greater Debye length.
  • The solution represented by the red curve has a greater Debye length.
  • Both have the same Debye length.
  • We don't have enough information to determine the Debye length.
slide5

In an ionic solution with a smaller Debye length, which of these effects will happen?a) Like-charged objects have a greater tendency to repelb) Like-charged objects have a smaller tendency to repelc) Oppositely charged objects have a greater tendency to attractd) Oppositely charged objects have a smaller tendency to attract
