Temperature, thermal equilibrium, and thermometry
Thermal contact and equilibrium, the zeroth law that makes a thermometer meaningful, thermometric properties, Celsius and kelvin, and constant-volume extrapolation to absolute zero; an empirical scale is only as linear as its working substance.

What this subsection covers
Thermal contact and equilibrium, the zeroth law that makes a thermometer meaningful, thermometric properties, Celsius and kelvin, and constant-volume extrapolation to absolute zero; an empirical scale is only as linear as its working substance.A strong response uses p-v and p-t state diagrams 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
What absolute-zero intercept and uncertainty do constant-volume pressure-temperature data support?

What absolute-zero intercept and uncertainty do constant-volume pressure-temperature data support? Useful evidence includes pressure-temperature pairs, a linear fit with residuals, the extrapolated intercept, propagated uncertainty, and a dead-volume systematic check.

This GioPhysics course map is an adaptable learning sequence, not academic credit, accreditation, or a universal university syllabus. Third-semester content is the least standardised of the introductory sequence: departments place oscillations, waves, optics, and thermal physics differently, and the modern-physics units here are a bounded survey rather than a complete course in relativity, quantum mechanics, atomic, nuclear, or particle physics. Follow your institution's published scope, notation, laboratory programme, and assessment rules. A result should be checked against units, signs, limiting cases, and the conditions under which its model was derived.
