Default Addiotional scalar properties: gas or liquid?

Hello,

I'm modeling one-step heptane combustion by the following reaction:

C7H16 + 11O2 -> 7CO2 + 8H2O,

where heptane and water are supposed to be in the gaseous state. The question is whether their properties specified in Additional scalars molecular properties panel should be the ones for gas or for liquid (as they are in the database).

Note: I've tried to supply manually an appropriate values for gases, but after the run they change to the ones of liquids (...kind of mystery?..)

Best Regards,

Julie
