Questions and Answers

What factors affect the rate of molecular diffusion?

  • Temperature, density, and particle shape
  • Viscosity, pressure, and particle size
  • Temperature, viscosity, and particle size (correct)
  • Temperature, pressure, and particle charge
  • What is the result of diffusion?

  • Complete immobilization of molecules
  • Gradual mixing of material leading to uniform distribution of molecules (correct)
  • Separation of molecules based on size
  • Formation of distinct layers of molecules
  • What happens once the concentrations of molecules are equal?

  • Molecules change direction of movement
  • Molecules continue to move, but the process of molecular diffusion has ceased (correct)
  • Molecules move faster to maintain the concentration gradient
  • Molecules stop moving completely
