Answer:
diffusion occurs in three of the states
but it is least in solids less in liguids and more n gases
diffusion in liquids
because of the inter cellar space is less in liquids so the rate of diffusion is less in liquid
ex: take acupuncture of water and mix a tea spoon full of bru or coffee powder .within few minutes the coffee powder spreads through diffusion
diffusion in gases
ex: lit a agarbatti in one of the room and a few minutes later the smell passes to other place through diffusion
as the inter cellular space is more the rate of evaporation is also more so it difussises fastly
