SUMMARY
The RMS speed of Helium atoms at a temperature of 247 K can be calculated using the equation RMS speed = sqrt(3RT/M), where R is the ideal gas constant, T is the temperature in Kelvin, and M is the molar mass of Helium in kg. Given that the atomic mass of Helium is 4.00 AMU, which converts to 6.64×10-27 kg, the RMS speed can be determined. If the temperature is doubled to 494 K, the RMS speed will increase, demonstrating the direct relationship between temperature and molecular speed.
