What is the main difference between diffusion and osmosis?
What is the main difference between diffusion and osmosis?
- Diffusion occurs in all states of matter, while osmosis only occurs in liquids
- Diffusion is the movement of particles from high to low concentration, while osmosis is the movement of water molecules from low to high concentration (correct)
- Diffusion only occurs through a selectively permeable membrane, while osmosis can occur through any membrane
- Diffusion is a passive process, while osmosis requires energy expenditure
How does an increase in temperature affect the rate of diffusion?
How does an increase in temperature affect the rate of diffusion?
- It increases the rate of diffusion (correct)
- It has no effect on the rate of diffusion
- It decreases the rate of diffusion
- It only affects the rate of diffusion in liquids, not gases
What factor has the greatest effect on the rate of diffusion?
What factor has the greatest effect on the rate of diffusion?
- Concentration gradient (correct)
- The type of substance diffusing
- Particle size
- Changes in temperature
