Standard temperature and pressure - Which combination of temperature and pressure correctly describes standard temperature and pressure, STP?

The answer is no.

In and , it is necessary to define the standard reference conditions of temperature and pressure when expressing a gas volume or a volumetric flow rate because the volume of a gas varies with the temperature and pressure of the gas.

When two objects of different temperatures come into contact, the higher energy particles the hotter particles will give energy to the lower energy particles until they all reach thermal equilibrium.

In this case, you may need to invest in a water separator or at least a saturation pressure dew point monitor in order to get the best FAD.
