However, it's important to note that "Freon" is a brand name, and many different chemicals are marketed under that name. Some of these chemicals can be liquids at room temperature, depending on their specific composition.

For example, R-134a (a common refrigerant used to replace older Freon types) is a gas at room temperature but can be a liquid under pressure.

So, to be precise, you need to specify which specific Freon you're asking about. But generally, Freons are considered gases under normal conditions.
