Ideal Gas Law Explorer

Solve the ideal gas relationship (PV = nRT) for pressure, volume, amount, or temperature, with common engineering units and traceable substitutions.

Tool Purpose & README

Purpose of This Tool

This tool supports quick state-point checks for ideal gases while keeping every step auditable. You pick one unknown, provide the other three quantities, and get the solved value in your selected units.

  • Single-equation solver for pressure, volume, amount, or temperature.
  • Unit-aware inputs (SI and common Imperial-friendly options).
  • Progressive disclosure: equation, substituted values, and SI verification.
  • Simple P-V isotherm visualization around the solved operating point.

Core logic lives in pycalcs/gases.py and is shared between tests and the browser UI.

P-V Isotherm Around Solution

Plot appears after calculation.

The curve is generated with solved n and T, using \(P = \frac{nRT}{V}\). The marker shows your solved state point.
