Question

The two containers of gas in FIGURE Q20.8 are in good thermal

contact with each other but well insulated from the environment. They

have been in contact for a long time and are in thermal equilibrium.

a. Is vrms of helium greater than, less than, or equal to vrms of

argon? Explain.

b. Does the helium have more thermal energy, less thermal

energy, or the same amount of thermal energy as the argon?

Explain.

Short answer

The solution gives thermal equilibrium

good thermal

contact with each other

Step-by-step solution

Description on thermal energy

It deals with the energy related to the temperature.

Description on the solution 

Provided solution$$\begin{gathered} \nu rms=\sqrt{\frac{3kbT}{{m_{molecules}}_{}}} \\ \nu rms\infty \sqrt{T},\nu rms\infty \frac{1}{\sqrt{m_{molecules}}} \end{gathered}$$
