Question:

The speed of sound is given by the relationship

1/2 CE RT Cy Csound м

where C_P is the constant pressure heat capacity (equal to C_V + R), R is the ideal gas constant, T is temperature, and M is molar mass.

a. What is the expression for the speed of sound for an ideal monatomic gas?

b. What is the expression for the speed of sound of an ideal diatomic gas?

c. What is the speed of sound in air at 298 K, assuming that air is mostly made up of nitrogen (B = 2.00 cm^€“1 and Î½Ì… = 2359 cm^€“1)?
