For example; the Boyle temperature of nitrogen is 50°C for hydrogen it is ?164°C whereas for helium it is ?250°C. The temperature at which real gases obey Boyle's law is called Boyle's temperature. It is denoted by TB and is derived from Vander Waal's equation...

 

This table gives a few thermodynamic data for hydrogen. Most values are those given in the NBS technical notes (reference 1) after conversion from the units used within those notes.

 

This web application provides access to a collection of critically evaluated thermodynamic property data for pure compounds with a primary focus on organics. These data were generated through dynamic data analysis as implemented in the NIST ThermoData Engine software package [1 2 3 4 5 6].

 

Thus in this work we provide the Boyle temperatures of 16 pure gases namely: argon carbon dioxide carbon monoxide deuterium helium-3 helium-4 hydrogen krypton methane neon nitric oxide nitrogen oxygen tetrafluoromethane tritium and xenon.

 

The hydrogen phase diagram shows the phase behavior with changes in temperature and pressure. The curve between the critical point and the triple point shows the hydrogen boiling point with changes in pressure.

 

The virial equation doesn't give a whole lot of clarity to what the Boyle temperature actually represents however other than a temperature where virial properties magically go to zero.

 

Since higher order virial coefficients are generally much smaller than the second coefficient the gas tends to behave as an ideal gas over a wider range of pressures when the temperature reaches the Boyle temperature (or when or are minimized).
