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 route, 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.
Primary move
Open topic route
No saved progress yet inside Rates and Equilibrium.
Entry diagnostic
Start from the opening step
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 route is the next guided collection step.
Reaction Rate / Collision Theory opens this track and sets up the rest of the path.
No saved progress yet inside Thermodynamics.
Grouped concept overview
Each group is authored in the topic catalog, 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.
比較粒子的平均運動與整體樣本的能量，改變物質量與加熱，並在同一個熱學實驗台上看相變平台如何打破只看溫度的直覺。

Open Temperature vs U在同一個受限粒子箱中連結壓力、體積、溫度與粒子數，然後把這些壓力變化再讀回粒子速度與碰壁頻率的改變。

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.
把熱看成由溫差驅動的能量轉移，同時比較傳導、對流與輻射如何在同一個小型熱學實驗台上競爭。
