The formula to calculate the room mean square speed is:
Since the given temperature is in °C, we need to convert it into Kelvin.
Helium (He) is the lightest noble gas component of air, and xenon (Xe) is the heaviest. [For this problem, use R = 8.314 J/(mol·K) and express ℳ in kg/mol.]
(a) Find the rms speed of He in winter (0.°C) and in summer (30.°C).
