Consider a container like that shown in Figure 20.12, with n₁ moles of a monatomic gas on one side and n₂moles of a diatomic gas on the other. The monatomic gas has initial temperature T_1i.

Figure 20.12

The diatomic gas has initial temperature T_2i.
a. Show that the equilibrium thermal energies are

b. Show that the equilibrium temperature is

c. 2.0 g of helium at an initial temperature of 300 K interacts thermally with 8.0 g of oxygen at an initial temperature of 600 K. What is the final temperature? How much heat energy is transferred, and in which direction?
