▸The final volume is 1.0000 L.
- The combined gas law P₁V₁/T₁ = P₂V₂/T₂ holds for a fixed amount of gas as it moves between two states.
- Every entry is converted to SI (pascals, cubic metres, kelvin) before solving, so you can mix atm, kPa, bar, mmHg, psi, litres, m³, °C, °F, and K freely.
- Across this process the pressure changes 2.00×, the volume 0.50×, and the absolute temperature 1.00×, and P×V/T stays constant.
Next stepSwitch the "Solve for" dropdown to a different variable and re-solve to verify the whole gas process is self-consistent.
