________ is Motion That Causes Molecules in Gases and Liquids

Question

________ is motion that causes molecules in gases and liquids to bump into adjacent molecules.
A) Diffusion
B) Brownian movement
C) Osmosis
D) Concentration gradient

Accepted Answer

Brownian movement is the motion that causes molecules in gases and liquids to bump into adjacent molecules. Diffusion is the movement of molecules from an area of high concentration to an area of low concentration. Osmosis is the diffusion of water molecules across a selectively permeable membrane from an area of high water concentration to an area of low water concentration. Concentration gradient is the difference in the concentration of a substance between two areas.
