After recovering refrigerant in the liquid phase, any remaining ______ is condensed by the recovery system.

In refrigerant recovery, you first remove the liquid refrigerant, and what remains is in vapor form. The recovery system includes a condenser that cools that vapor so it changes back into a liquid, allowing it to be collected and stored. The other forms don’t fit this step: liquid is already liquid and wouldn’t be condensed again, oil isn’t the refrigerant that’s being condensed, and while “gas” could describe the same state, industry practice uses “vapor” to refer to the refrigerant in its gaseous phase that the condenser targets for condensation.
