Speed of Sound in Solids, Liquids, and Gases - Physics Practice Problems
Показать описание
This physics video tutorial provides a basic introduction into the speed of sound in solids, liquids, and gases. It contains plenty of examples and practice problems. In a solid, the speed of sound depends on the density of the material and young's modulus - also known as the elastic modulus. In a liquid, the speed of sound depends on the density of the fluid and the bulk modulus. In a gas, the speed of the sound depends on gamma - the ratio of heat capacities, the temperature, and the molar mass of a gas. As the temperature increases, the speed of sound in air increases. The speed of a solid is higher than the speed of sound in a liquid which in turn is higher than the speed of sound in a gas. All of the equations and formulas that you need are provided. This video contains examples and practice problems of calculating the speed of sound in steel, the speed of sound in water, and the speed of sound in air.
