Formula and methodology
Formula: V₂ = V₁(T₂ in K)/(T₁ in K) at constant pressure.
The proportional relation requires Celsius inputs to be converted to kelvin before the ratio is applied.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Initial volume — L; minimum 1.0E-6; maximum 1000000000
- Initial temperature — °C; minimum -273.149999; maximum 100000
- Final temperature — °C; minimum -273.149999; maximum 100000
Worked example
| Input | Value |
|---|---|
| Initial volume | 2 |
| Initial temperature | 20 |
| Final temperature | 80 |
Final volume ≈ 2.409 L.
Assumptions and limits
- Temperatures must be above absolute zero and volume is positive.
- Pressure and amount of gas remain constant; the ideal-gas approximation is used.
- Container flexibility, phase change, nonideal behavior, and pressure variation are not modeled.
