1.

Estimate the thermal speed of an oxygen molecule at room temperature.

Hint:

There are N_A molecules in $1\,\mathrm{mol}$

2.

Calculate the chemical potential of ideal gas $\mu=(\partial A/\partial N)_{T,V}$.

3.

Calculate the energy of the ideal gas without internal degrees of freedom ($q_{\text{internal}}=1$). If you are too lazy (or too smart) to calculate it from equation (6), try to guess the answer. How would you do this?
