What does cfm stand for?

In science, cfm stands for chlorofluoromethane, and is more commonly known as Freon 31. Chlorofluoromethane is any of a series of gaseous or volatile methanes replaced by chlorine and fluorine and having little or no hydrogen.

Chlorofluoromethane has been used as a refrigerant and aerosol propellant. It is no longer used as an aerosol propellant due to concern from scientists about the potential relation of its use to the depletion of the ozone layer. Chlorofluoromethane is a hydrochlorofluorocarbon, otherwise known as an HCFC. HCFCs have been thought by scientists to deplete the ozone layer. The ozone depletion potential of chlorofluoromethane is 0.02.
