Diffusion is:the movement of a substance from a low concentration to a high concentration.the movement of a substance from a high concentration to a low concentration.the movement of a substance from high concentration to a high concentration.the movement of a substance from low concentration to a low concentration.

Fill in the blanks below to describe the process of diffusion.Diffusion is the net movement of particles from a region of concentration to a region of concentration until both regions are of concentrations.

Which important word is missing from the definition of diffusion below?The spreading out of particles of a gas, or any substance in solution, resulting in the movement from an area of higher concentration to an area of lower concentration.netsolidsmovementliquid

Diffusion occurs when a substance is at aconcentration in one region, and at a lower concentration in another region. This differencein is called the concentration .
