Question

What is the average kinetic energy per molecule of neon gas at 32°C?
What is the root-mean-square speed of neon atom at the temperature?​

Answer 1

Answer:

Since both Helium and Neon are monoatomic gases, degree of freedom for each gas is f=3. From ideal gas theory, average kinetic energy is equal to the thermal energy. Hence

Answer 2

Answer:

This means that there is also a relationship between RMS speed and temperature. The average kinetic energy (K) is equal to one half of the mass (m) of each gas molecule times the RMS speed (vrms) squared.
