1.	What are the application of diffusion in chemistry?
Answer» \tWe get the smell of our favourite food sitting in the drawing room even when the food is being cooked in kitchen. The vapor coming out from the food reaches to us because of diffusion in air and we get the smell of food.\tWe get the smell of burning incense stick sitting far from it. When an incense stick is burnt, the incense present in it vaporizes because of heat. The vapor coming out from the incense stick mixes with air and reaches to us.\tIn similar way we sense the good or bad smell from a distance.\tWhen sugar is added in water, it is mixed because of the diffusion. The particles of sugar collide with the particles of water because of their continuous movement. And finally they are mixed together because of diffusion.\tCarbonated drinks are prepared by the diffusion of gas in water. We notice a hiss sound when the cap of bottle of a carbonated drink is open, the hiss sound comes because of the diffused gas coming out of water. Soda, Soft drinks (coca-cola) etc. are the carbonated drinks and prepared mainly because of the diffusion of carbon dioxide in water.\tAquatic animals take dissolved oxygen in water while breathing. Aquatic plants synthesize their food under water because of the dissolved carbon dioxide in water. These gases dissolved in water because of the diffusion.
