Exercise on Finding Finding the RMS Speed of He atom: Solutions
Questions: What is the rms speed (u) of a He atom at 25°C?
Solution:
Knowing the molar mass of He (in Kg/mol), the temperature (25+273.15) in K,
and the gas constant (8.314 kg m2/s2 mol K),
→ it is very simple to find out its rms speed.
