Three quadratic translational terms contribute RT/2 each per mole. Therefore U=(3/2)(14)R(420).
Work is positive for expansion; the process is reversible and isothermal for an ideal gas.

UniversityConnect rotation, oscillations, central forces and continuous wave models.
Work with Gauss laws, electrical field models, thermodynamic laws and electromagnetic waves.
Compare relativistic measurement with quantum states, the Schrödinger equation and uncertainty.
Use Lagrangian and Hamiltonian methods, then interpret canonical ensembles.
Explore perturbation theory, scattering, variational quantum estimates and a conceptual bridge to general relativity.
