The aroma of food comes from the kitchen because of-
(a) Osmosis
(b) Diffusion
(c) Convection
(d) Fragmentation
Correct Answer: (b) Diffusion
Explanation:
Diffusion is the movement of a substance from a high concentration area to a low concentration area.It happens in liquids and gases because their particles move randomly from place to place.
1) When perfume is sprayed in the corner of a room, the scent of it fills the complete room.
2) When a drop of blue ink is added to water, complete water slowly takes the blue color due to the diffusion of ink color into the water.
