Questions and Answers

What factors affect the rate of molecular diffusion?

  • Temperature, viscosity, and particle size (correct)
  • Surface area, concentration, and color
  • Pressure, density, and particle charge
  • Velocity, volume, and molecular weight
  • What is the result of molecular diffusion in terms of material mixing?

  • Random distribution of molecules with no uniformity
  • Complete separation of different types of molecules
  • Formation of distinct layers of molecules
  • A gradual mixing of material resulting in uniform distribution of molecules (correct)
  • What happens to molecular diffusion when concentrations become equal?

  • Molecules continue to move, but the process is governed by self-diffusion (correct)
  • Molecules stop moving completely
  • Molecules transform into a different state
  • Molecules move in the opposite direction
  • What term is used to describe the state when molecules are still in motion, but an equilibrium has been established?
