1. Two gasses are in thermal equilibrium in a closed container: 2 moles of H 2 (Hydrogen has atomic mass 1) and 4 moles of He (noble gas, atomic mass 4). a) Explain which substance has more total thermal energy. Assume that each molecule of H 2 has 5 active modes. b) Explain which is moving faster, a H 2 molecule or a Helium atom? 2. If you have two types of molecules and one has twice as many ways of absorbing energy as the other, what can you
