What factors affect the rate of molecular diffusion?
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?
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?
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
