Matter in Motion: Phase and Energy
Like Duolingo, but for Matter in Motion: Phase and Energy. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
For the part of you with thirty open tabs that never became anything.
A short one: 9 levels across 2 sections, about 18 minutes end to end, roughly 4 days at five minutes a day. It moves through The Dance of Particles and The Rules of the Quantum World. It assumes you already know the basics.

Key ideas in Matter in Motion: Phase and Energy
- Added energy is consumed by breaking intermolecular bonds during phase transitions
- Lower atmospheric pressure allows molecules to escape into gas at lower temperatures
- Temperature measures average kinetic energy, which remains constant during a plateau
- Boiling occurs when vapor pressure equals the surrounding atmospheric pressure
- Why temperature plateaus during a phase change
- The effect of atmospheric pressure on boiling point
- The triple point requires a specific, unique combination of temperature and pressure
- Sublimation occurs when a solid's vapor pressure exceeds ambient pressure before it melts
- At this point, small changes can shift the substance into any of the three states
- Dry ice (solid CO2) sublimes at room pressure because its liquid phase requires high pressure
- Conditions required for sublimation versus melting
- The fastest, highest-energy molecules are the first to break free into the air
- The unique conditions of the triple point
- The loss of high-energy molecules reduces the average kinetic energy of the liquid left behind
- The mechanism of evaporative cooling
- Existing chemical bonds must be destabilized before atoms can rearrange
You've tried the other tabs
Thirty open tabs. Four facts you actually kept.
You watched. You nodded. By Sunday it was gone.
One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives Matter in Motion: Phase and Energy the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
Here's what playing it feels like
A real question from this course. Take your best guess.
If you are cooking on a high mountain where the air is thin, what happens to the boiling process?
