Diffusion of gases
Diffusion of gases
Diffusion of gases: gas particles move with high speeds and the intermolecular spaces in gases are very large. These properties allow a gas to diffuse easily into another. Thus, gases mix together spontaneously, despite their differences in densities. When a bottle of perfume is open in the corner of a room, the fragrance of the perfume spreads in air and covers the entire space of the room. Also the smell of the food being cooked in the kitchen reaches our nostrils, even if we are not physically present in the room. This is because the particles constituting the smell mix with the particles of air, spread out and reach our nostrils. Other examples include virus on sneezing, dissolution of oxygen and carbon dioxide in sea water etc.
Which of the following are correct : (a) Gas particles move with high speeds and the intermolecular spaces in gases are very large. (b) High speeds and the intermolecular spaces in gases are very large which allow a gas to diffuse easily into another. (c) Gases mix together spontaneously, despite their differences in densities. | |||
