Problem 75P

The speed of propagation of a sound wave in air at 27°C is about 350 m/s. Calculate, for comparison, (a) ??? for nitrogen molecules and (b) the rms value of ??? , at this rms x? temperature. The molar mass of nitrogen (N? ) is 28.0 g/mol. 2?

Step-by-Step Solution:

Solution 75P Step 1: 3kT v rms = M Where, k - Boltzmann constant T - Temperature of the gas M - Molar mass
