If the temperature is low enough the gas can condense and turn into a liquid.

The critical temperature is the temperature below which a gas can condense into a liquid.

The gas collected from this condenses into aqua fortis.

Thus cooled, the pressurized gas condenses to a liquid.

At this point the gas will condense at the same rate as the liquid evaporates.

A liquid at its boiling point will evaporate more quickly than the gas can condense at the current pressure.

It's getting much colder, and the gas in the bag is condensing more than I thought it would.

The hot gas runs through a set of hot coils and condenses into a liquid until it reaches an expansion valve.

The gases condense into ice that falls to the moon's surface, he said.

With this ratio, the team was able to understand more clearly how interstellar gas condenses to form solid matter.
