The molecular weight of R11 refrigerant is 137.4 and its boiling point is 74.7 degree F. Freon is a gas that's used for cooling. R-22, the principle component in Freon, has been banned, along with other greenhouse gases, due to evidence that they damage the Earth’s ozone layer and contribute to global warming. When the Freon gas is compressed, its pressure rises, making it very hot. The longer answer is, it depends on what type of oil and system pressure your air conditioner uses. They are stable, nonflammable, low toxicity gases or liquids which have generally been used as refrigerants and as aerosol propellants. Many modern refrigerants are man-made halogenatedgases, especially fluorinated gasesand chlorinated gases, that are frequently referred to as Freon(a registered trademark of Chemours).

Refrigerator Freon is the name for the cooling liquid refrigerant that is used in the heating and cooling process of refrigerators, as well as a number of other household appliances. R-22 is non-flammable and non-toxic, with a fairly low heat transfer coefficient that makes it an ideal refrigerant for home AC use. Kettering patented a refrigerating apparatus to use the gas; this was issued to Frigidaire, a wholly owned subsidiary of General Motors.[5]. The result is low-pressure Freon gas. The term "freon" is a common descriptor or proprietary eponym (similar to a generic trademark) like "xerox" , "frosted flakes" or "kleenex".

It has many uses and is known even by individuals outside of the HVAC profession. Refrigerator Freon is the name for the cooling liquid refrigerant that is used in the heating and cooling process of refrigerators, as well as a number of other household appliances. The Freon liquid then flows through an expansion valve, which causes it to cool down until it evaporates. These gases, which have very low evaporation points, are condensed under pressure to chill the air. If it says R-410A, then you have a modern replacement.
