Combined Gas Law Calculator
Calculate the final pressure after volume and temperature changes.
Instructions
Enter initial pressure, volume, temperature (in kelvins), and final volume and temperature. The tool computes final pressure.
Formula
P₁V₁/T₁ = P₂V₂/T₂
P in Pa, V in m³, T in K.
About the Combined Gas Law
Relates pressure, volume, and temperature of a fixed amount of ideal gas between two states.
Common Questions
Can I input °C?
Convert to kelvins: T(K) = T(°C) + 273.15.
Does n change?
No, it assumes a closed amount of gas (n constant).
