Thermodynamics and Kinetic Theory

Not started

Start with temperature-versus-internal-energy bookkeeping, reuse that particle story for gas pressure, then follow energy transfer into heating curves and phase-change shelves.

Use this track when thermal ideas still feel split between temperature, pressure, heat flow, and heating curves. The path stays bounded: Temperature and Internal Energy fixes the bookkeeping, Ideal Gas Law and Kinetic Theory reuses that same particle picture for pressure, Heat Transfer keeps energy crossing a boundary instead of turning into a stored substance, and Specific Heat and Phase Change closes by showing what the transferred energy does inside the sample.

Entry diagnostic

Decide where to enter this path without opening a second testing system.

Reuse the temperature quick test and the existing gas-pressure compare challenge to see whether the particle-energy story is already stable enough to jump straight into boundary heat flow.

Why this order

The sequence is authored to keep the model honest.

Temperature and Internal Energy comes first because the later thermal branch is harder to trust if average microscopic motion and whole-sample energy are still being treated as the same thing. Ideal Gas Law and Kinetic Theory then keeps that same particle picture but turns it into pressure, volume, and collision reasoning. Heat Transfer follows the energy across a boundary without leaving the same causal story, and Specific Heat and Phase Change closes by keeping the energy bookkeeping honest on both sloped heating segments and the flat shelf.

Shared concept pages

Each step opens the same simulation-first framework.

Compare mode, prediction mode, quick test, worked examples, guided overlays, challenge mode, and read-next cues stay on the concept pages. The track only decides the guided order and the next recommended stop.

  1. 1Not startedMastery: NewStart here

    Temperature and Internal Energy

    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.

    Start here before moving into Ideal Gas Law and Kinetic Theory.

    Ideal Gas Law and Kinetic Theory

    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.

    Builds on Temperature and Internal Energy before setting up Heat Transfer.

  3. Checkpoint 1LockedNot started

    Gas-pressure bridge checkpoint

    Match the same pressure with a cooler denser setup so the particle bookkeeping and the gas-state law stay tied to one microscopic story.

    Finish Ideal Gas Law and Kinetic Theory first. This checkpoint ties together Temperature vs U and Ideal gas law through Match pressure with a different microscopic story.

    Heat Transfer

    See heat as energy transfer driven by temperature difference while conduction, convection, and radiation compete on one compact bench with honest pathway rates.

  5. Checkpoint 2LockedNot started

    Heat-flow checkpoint

    Keep the same temperature contrast while slowing the loss so heat stays an energy-transfer story tied to the path rather than a stored substance.

    Finish Heat Transfer first. This checkpoint ties together Temperature vs U and Heat transfer through Same contrast, slower loss.

    Pause here after Heat Transfer before moving into Specific Heat and Phase Change.

    Specific Heat and Phase Change

    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.

  7. Checkpoint 3LockedNot started

    Heating-curve checkpoint

    Close the track by pausing on a true shelf where energy still moves while temperature stays nearly flat, so the whole thermal story remains internally consistent.

    Finish Specific Heat and Phase Change first. This checkpoint ties together Temperature vs U, Heat transfer, and Specific heat and phase change through Catch the real shelf.
