ON THE PROBLEM OF PROPAGATION OF SOUND VELOCITY IN GASES AND HISTORY OF ITS DEPENDENCE ON HEAT CAPACITY

This article examines the speed of propagation of elastic waves in media: longitudinal (in gases, liquids or solids) and transverse, movement (in solids), which is determined by the elasticity and density of the medium: as a rule, the speed of sound in gases is greater than in liquids , less, and in liquids less than in solids. It was also mentioned that the speed of sound in gases depends on the temperature of the substance, and in single crystals - on the direction of wave propagation.
