Question

what is diffusion how the rate of diffusion affected with increase in temperature pressure density​

Answer 1

Answer:

Diffusion is the process of movement of particles or molecules from higher concentration to lower concentrations through a semi permeable membrane.

Explanation:

On increasing temperatures the kinetic energy of molecules increases so diffusion also increases.

On increasing pressure molecules come closer and collide so they move faster.

Increasing density the molecules become heavy so diffusion is decreased.

Hope it helps you

Answer 2

Diffusion is the movement of particles from higher concentration to a lower concentration until they are spread out evenly. For example- It occur in singled-cell organism like chlamydomonas and simple multicellular plant like spirogyra.
