Oxygen

Overview

Engineering reference data for Oxygen in gases and compressed air.

Key Formulas

Ideal Gas Law

$PV = nRT$

Pressure × Volume = moles × gas constant × temperature.

Boyle's Law

$P_1 V_1 = P_2 V_2$

At constant temperature.

Charles's Law

$\frac{V_1}{T_1} = \frac{V_2}{T_2}$

At constant pressure.

Variables

Symbol	Description	Unit
$P$	Pressure	Pa
$V$	Volume	m³
$T$	Temperature	K
$R$	Gas constant	8.314 J/(mol·K)

Specific Heat Data

Notes

The specific heat values, including isobaric specific heat ($C_p$) and isochoric specific heat ($C_v$), vary with temperature. At high temperatures above 1500 K, dissociation of oxygen gas becomes appreciable, making pressure a significant variable in specific heat calculations. The tabulated values apply to undissociated states.
