What this subsection covers
The Maxwell–Boltzmann distribution, the distinction between most-probable, mean, and rms speeds, how temperature and molar mass reshape the curve, and the mean free path between collisions.A strong response uses heating and cooling curves and states where the model stops being reliable.
Reasoning checklist
Evidence, assumptions and limits
Assumptions to state
State the system, observable, approximation, and conditions held fixed before using a model.
Evidence to collect
Can an energy-conservation model predict the equilibrium temperature of a mixture within uncertainty?

Can an energy-conservation model predict the equilibrium temperature of a mixture within uncertainty? Useful evidence includes mass and temperature data, a heat-loss estimate, predicted versus measured equilibrium, propagated uncertainty, and discrepancy analysis.

This GioPhysics course map is an adaptable learning sequence, not academic credit, accreditation, or a universal university syllabus. Departments may redistribute weeks, laboratory hours, optics, or the modern-physics survey to match local requirements. Thermal physics appears as an unnumbered institutional extension: some universities assess it within Physics II, while others teach it in a separate course, so include the thermal extensions only where the local syllabus requires them. A result should be checked against units, signs, limiting cases, and the conditions under which its model was derived.
