Now, solve this: the hot chocolate effect, this quantity is reduced because of bubble density, which occurs due to the addition of fine powders to liquids. The mass specific total enthalpy in perfect gas compressible flow is equal to a term featuring this quantity squared multiplied by quantity one plus partial derivative of pressure with respect to energy multiplied by M squared, end quantity. For an ideal gas, this is given by the square root of the adiabatic index times pressure divided by density, and it is generally given by the square root of the bulk modulus divided by density. Generally approximated as 331 meters per second in dry air at 0 Celsius, the speed of an object divided by this quantity is known as the Mach number. For 10 points, name this quantity defined as the rate at which waves that transfer noise move through an elastic medium.
