Combined/Boyle's/Charles's/Gay-Lussac's Law Calculator implementation

Binding contract

This record describes what an executable surface must bind and validate. It does not claim that a public calculator, package, or production route is deployed.

Computation or source lookup only

Input and validation requirements

The specification exposes a division-by-zero case at 0 K and does not state temperature-unit validation or an explicit Kelvin conversion requirement. The selectable-law toggle also produces materially different results unless the held-fixed variable is enforced.

Required corrections

No binding erratum is attached to this unique-name record. Implementers must still preserve the declared units, domain, and failure behavior.

Inspectable interface fixture

The sample below is evidence for interface and validation tests, not a production implementation.

{
  "inputs": {
    "law": "Boyle's law",
    "P1_kPa": 101.325,
    "V1_L": 2,
    "P2_kPa": 202.65
  },
  "expected_outputs": {
    "V2_L": 1
  },
  "working": "P1V1=P2V2. Solve V2=(P1V1)/P2. V2=(101.325 kPa × 2.00 L) / 202.65 kPa = 202.65 kPa·L / 202.65 kPa = 1.00 L."
