Governing equation

\frac{\partial u}{\partial t} = 0.12 \nabla^{2} u = 0.12 (u_{xx} + u_{y y} + u_{z z})

Reading this result: Heat spreads outward at a rate set by the diffusivity — each cell relaxes toward the average of its six neighbors every step.

A phase diagram maps which state — solid, liquid, or gas — a substance takes at each temperature and pressure. The lines are phase boundaries; cross one and the material transforms. All three meet at the triple point, and the liquid-gas line ends at the critical point beyond which liquid and gas become indistinguishable.

Pressure100 kPa

Governing equation

\frac{d P}{d T} = \frac{L}{T Δ V}, T = 298.1 K, P = 100 kPa

Reading this result: Liquid: warm enough to melt yet below the boiling line at this pressure, so the stable state is liquid water.
