Overview

Engineering reference data for Butane in gases and compressed air.

Key Formulas

Ideal Gas Law

PV=nRTPV = nRT

Pressure × Volume = moles × gas constant × temperature.

Boyle's Law

P1V1=P2V2P_1 V_1 = P_2 V_2

At constant temperature.

Charles's Law

V1T1=V2T2\frac{V_1}{T_1} = \frac{V_2}{T_2}

At constant pressure.
