Use the general relation for the speed of sound in Equation 13.3 together with the ideal gas law (see Chapter 15 if you need a refresher on the ideal gas law) to show that the speed of sound in a gas can be written as where P is the pressure. Can you give an intuitive explanation of why increases as the pressure is increased?

(reference equation 13.3)
