The Property command can be used to find all information available through the ThermophysicalData package. It calls one of the following commands:

ThermophysicalData[Chemicals][Property] to find data available through the ThermophysicalData[Chemicals] subpackage

ThermophysicalData[CoolProp][Property] to find data available through the ThermophysicalData[CoolProp] subpackage

ThermophysicalData[Atmosphere][Property] to find data available through the ThermophysicalData[Atmosphere] subpackage

Every calling sequence of these commands is supported.

If no source option is given, then Maple tries calling all three commands. If exactly one of the three commands returns without error, that value is returned; otherwise, an error is signaled.

In the case where no source option is given, one can obtain some information about the process of selecting a suitable source by setting the infolevel for ThermophysicalData to 2 or (for more verbose information) 3.
