Diffusion is the net (overall) movement of particles from an area of high concentration to an area of lower concentration.Question 4Answera.Falseb.True

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 of the following is true about diffusion?Multiple choice question.Molecules move against their concentration gradients.Molecules move down their concentration gradients.

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.

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 .

Which of the following is the best definition of diffusion?The spreading out of particles of a gas, or any substance in solution, resulting in a net movement from an area of higher concentration to an area of lower concentration.The spreading out of particles of a solid, or any substance in a solution, resulting in a net movement from an area of higher concentration to an area of lower concentration.The spreading out of particles of a gas, or any substance in solution, resulting in a net movement from an area of lower concentration to an area of higher concentration.The spreading out of particles of a gas, liquid or solid, resulting in a net movement from an area of higher concentration to an area of lower concentration.
