#### Answer:

#### Explanation:

The average speed of the

The average kinetic energy can be estimated using the equipartition principle. This principle says that in every degree of freedom there is on average the same amount of kinetic energy.

In thermal equilibrium (the state variables (P, V, n, T) do not change) with high temperature, the average amount of kinetic energy in each degree of freedom is directly related to the temperature, therefore:

With

Since the temperature is not given, we cannot determine the average kinetic energy.

**Degrees of freedom**

A

We have 1 mol of

We have in total:

The total kinetic energy of 1 mol of

Now we only need the temperature to calculate the correct number.
