What factors affect the rate of molecular diffusion?
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?
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?
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
