Question

Define diffusion ? Explain the rate of order of diffusion in solid ,liquid and gases ?state the effect of temperature in diffusion? 5marks

Answer 1

the action of spreading the light from a light source of evenly to reduce clear and her Shadows .

Answer 2

intermixing of particles of different types of matter by their own.In solid diffusion can take place but it need physical force .In liquid diffusion takes fast.In gas there are intermolecular spaces more so it diffuse faster.If the temperature increases the kinetic energy of particles also increases and move faster.
