Define the wavelength of sound in terms of successive compressions of air

The pressure, volume, and temperature of a mole of an ideal gas are related by the equation pv = 8.31t, where p is measured in kilopascals, v in liters, and t in kelvins. use differentials to find the approximate change in the pressure if the volume increases from 14 l to 14.6 l and the temperature decreases from 375 k to 370 k. (round the answer to two decimal places.)

What is relative velocity? in which condition is relative velocity known by adding the velocity of the first body and that of the second body
