Latent Heat & Enthalpy API
Latent-heat and phase-change enthalpy as an API, computed locally and deterministically. The latent endpoint applies Q = m·L — the heat to melt, freeze, boil or condense a substance equals its mass times the latent heat — and solves for whichever of the heat, the mass or the latent heat you leave out, taking the latent heat of fusion or vaporization directly or from a built-in substance table (water, ethanol, mercury, lead, aluminium, iron, nitrogen, oxygen). The phase-change endpoint computes the full enthalpy of heating or cooling a substance from one temperature to another, automatically combining the sensible heat m·c·ΔT within each phase with the latent heat at every melting and boiling transition it crosses, and returns a step-by-step breakdown — so it can tell you, for example, the total energy to turn ice at −10 °C all the way into steam at 110 °C, using the right specific heat for the solid, the liquid and the gas. The substances endpoint lists the latent heats and per-phase specific heats. Heat is reported in joules, kilojoules, watt-hours and kilocalories. Everything is computed locally and deterministically, so it is instant and private. Ideal for thermodynamics and HVAC tools, refrigeration, heating and process-engineering apps, food and material science, and physics education. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is latent heat and phase change; for sensible heat alone (Q = m·c·ΔT with no phase change) use a specific-heat API.
