Is condensate gas or liquid?

Condensate is strictly a liquid substance rather than a gas. By definition in thermodynamics and industrial nomenclature, condensate is the specific fluid phase that results when a vapor or gas loses thermal energy and undergoes a complete phase transition into liquid form. While the material originates as a vapor or gas under specific temperature and pressure conditions—such as underground hydrocarbon reservoirs or humidity in household air—once it crosses the saturation point and liquefies, the resulting product is entirely liquid. For instance, natural gas condensate exists as a gas deep underground under immense pressure and heat, but once it is extracted to the surface and exposed to normal atmospheric conditions, it condenses into a clear, ultra-light liquid hydrocarbon. Similarly, water condensate in an air conditioning system starts as invisible water vapor gas in the air before condensing into liquid droplets on the cold coils. Across every scientific, mechanical, and commercial application, condensate is always classified and handled as a liquid.
