Bulk modulus of air at 20 degrees celsius
WebIn simpler words, the bulk modulus is nothing but a numerical constant that is used to measure and describe the elastic properties of a solid or fluid when pressure is applied to all the surfaces. The bulk modulus of elasticity is one of the measures of the mechanical properties of solids. Other elastic modules include Young’s modulus and ... WebAt 20 °C (68 °F), the speed of sound in air is about 343 metres per second (1,125 ft/s; 1,235 km/h; 767 mph; 667 kn ), or one kilometre in 2.91 s or one mile in 4.69 s. It depends strongly on temperature as well as the medium through which a sound wave is propagating.

WebBulk Modulus for Gases Gases have an equation of state that connects pressure, density and temperature i.e., equation of state. This enables us to deduce an explicit relationship between pressure and density. Such a relationship depends upon the process being considered - isothermal (at constant temperature) or isentropic (at constant entropy).
