Answer:
Air is a homogeneous mixture of the gaseous substances nitrogen, oxygen, and smaller amounts of other substances. Salt, sugar, and many other substances dissolve in water to form homogeneous mixtures. A homogeneous mixture in which there is both a solute and solvent present is also a solution.Sound waves are created by help of the disturbances in the medium. The individual particles in the air are not transmitted with the wave, but actually the propagation of the wave is what causes the particles, i.e. (molecules of the air) oscillate about an equilibrium position.
