Thermal Physics

Overview

This page is now a transition hub. The old broad Thermal Physics chapter has been split into two separate topics so the content is easier to study and maintain:

Use this page primarily as a navigation point during the transition.

Core Ideas

The split follows the natural syllabus boundary:

  • Thermal Physics A focuses on macroscopic thermal ideas such as temperature scales, thermal equilibrium, heat capacity, latent heat, calorimetry, heating curves, and thermal practicals.
  • Thermal Physics B focuses on microscopic and thermodynamic ideas such as kinetic theory, ideal gases, internal energy, the first law, thermodynamic processes, and p-V diagrams.

Exam Relevance

If a question is about thermometer calibration, mixing, latent heat, or electrical thermal methods, go to Thermal Physics A.

If a question is about gas laws, rms speed, internal energy of ideal gases, first-law sign conventions, or p-V graphs, go to Thermal Physics B.

Where To Go

Thermal Physics A

Use Thermal Physics A for:

  • temperature and thermal equilibrium
  • thermometric properties
  • Celsius and Kelvin scales
  • heat capacity and specific heat capacity
  • calorimetry and mixing
  • latent heat
  • heating curves
  • electrical determination of thermal quantities

Main support notes:

Thermal Physics B

Use Thermal Physics B for:

  • kinetic theory of matter
  • internal energy
  • changes of state from particle viewpoint
  • ideal gases and gas laws
  • ideal gas equation
  • rms speed
  • work done by gases
  • first law of thermodynamics
  • thermodynamic processes
  • p-V diagrams and cycles

Legacy Notes

Some older broad notes still remain in the repo as bridge material during migration, for example:

These are no longer the main canonical structure.

Summary

The old Thermal Physics chapter has been deliberately split into:

Use those two topics as the main revision route from now on.
