Which has more internal energy at room temperature—a mole of helium or a mole of air?

Explain qualitatively the basis for the Boltzmann distribution. Never mind the details of the math for the moment. Focus on

the trade-offs involved with giving energy to a single oscillator vs. giving that energy to a large object.
