Question

Quizplus · Accepted Answer

Diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration. This occurs spontaneously as the molecules spread out and become more evenly distributed. Conduction refers to the transfer of heat or electricity through a material, solution is a mixture of two or more substances, and evaporation is the process by which a liquid turns into a gas.
