Idealized SI-unit model for educational estimates. Confirm material properties, boundary conditions and applicability before engineering use.

Formula

P₁V₁/T₁=P₂V₂/T₂

Find a final volume when pressure and temperature change.

Worked example

Initial absolute pressure (Pa)
100000
Initial volume (L)

Initial temperature (K)
300
Final absolute pressure (Pa)
200000
Final temperature (K)
300
Final volume
5 L

Scope and limitations

Idealized SI-unit model for educational estimates. Confirm material properties, boundary conditions and applicability before engineering use.

Inputs are checked for missing values and allowed ranges. A result outside the finite numeric range is not displayed. Rounding affects display, while the calculation uses the model’s numeric precision.

Check your units and assumptions before relying on a result. Changing a label does not convert a currency or physical unit.
