Detailed explanation-1: -The neighbors are cooking on the grill!. is that osmosis or diffusion??? Answer: Diffusion is the correct answer.

Detailed explanation-2: -For example, when someone sprays perfume and the “scent molecules” gradually spread out in the room so that everyone can smell the perfume-that’s diffusion.

Detailed explanation-3: -In diffusion, particles move from an area of higher concentration to one of lower concentration until equilibrium is reached. In osmosis, a semipermeable membrane is present, so only the solvent molecules are free to move to equalize concentration.

Detailed explanation-4: -Osmosis and Diffusion Examples Plant root hairs uptaking water is another example of osmosis. Diffusion Examples: A good example of diffusion is the way perfume fills an entire room. Another example is the movement of small molecules and ions across the cell membrane.

Detailed explanation-5: -Osmosis is a type of simple diffusion in which water molecules diffuse through a selectively permeable membrane from areas of high water concentration to areas of lower water concentration.
