Separate temperature from total internal energy, bridge that microscopic story into gas pressure and the ideal-gas law, then follow how thermal energy crosses boundaries and shapes honest heating curves on one compact thermal branch.
Use this topic page when you want the thermal story to stay causal instead of formula-first. Temperature and Internal Energy separates average microscopic motion from whole-sample energy, Ideal Gas Law and Kinetic Theory turns that same particle picture into pressure-volume-temperature reasoning, Heat Transfer follows energy across a boundary, and Specific Heat and Phase Change shows what that transferred energy does next inside the sample.
Best first concepts
The topic page keeps these starts in their own compact row so the first screen is about orientation and next action, not stacked feature cards.
Compare average particle motion with whole-sample energy, vary amount and heating, and see why a phase-change shelf breaks naive temperature-only reasoning on one compact thermal bench.
Thermal foundations
Strong first stop for getting into this topic without scanning the whole library.
Connect pressure, volume, temperature, and particle number on one bounded particle box, then read the same pressure changes back as changes in particle speed and wall-collision rate.
Gas-state bridge
Strong first stop for getting into this topic without scanning the whole library.
See heat as energy transfer driven by temperature difference while conduction, convection, and radiation compete on one compact bench with honest pathway rates.
Heat flow
Strong first stop for getting into this topic without scanning the whole library.
See why the same energy pulse changes different materials by different temperature amounts, and why a phase-change shelf can absorb or release energy without changing temperature on one compact thermal bench.
Thermal response

Specific learning goals
These goal cards stay authored and transparent. They reuse the current topic page, starter tracks, guided collections, concept bundles, and progress cues instead of adding a separate recommendation system on top of this branch.
Use the chemistry topic page, the new Rates and Equilibrium Lesson Set, the compact starter track, and the thermodynamics topic page so the chemistry pilot feels like a real branch instead of isolated concept links.

No saved diagnostic checks are available yet, so the opening step is still the best entry into the collection.
Reuses the guided collection entry for Rates and Equilibrium Lesson Set, with 0 of 2 probes already ready.
No saved progress yet inside Rates and Equilibrium.
Open the rates-and-equilibrium topic page is the next guided collection step.
Reaction Rate / Collision Theory is the next best step inside Rates and Equilibrium.

Grouped concept overview
Each group is authored for this topic, but the actual concepts, progress badges, and track cues still come from the canonical concept metadata and shared progress model.
Group 01
Start with the particle-energy bookkeeping, then reuse that same microscopic picture to explain why gas pressure changes when temperature, volume, or particle number changes.
Compare average particle motion with whole-sample energy, vary amount and heating, and see why a phase-change shelf breaks naive temperature-only reasoning on one compact thermal bench.

A strong first concept for opening concepts without committing to a full track.
Connect pressure, volume, temperature, and particle number on one bounded particle box, then read the same pressure changes back as changes in particle speed and wall-collision rate.

Group 02
Once the particle picture is stable, follow how energy crosses a boundary and how specific heat and latent heat shape the thermal response inside the sample.
See heat as energy transfer driven by temperature difference while conduction, convection, and radiation compete on one compact bench with honest pathway rates.
