The Refrigerant ‘FREON’ is A. Calcium Tetra Fluoride B. Difluoro Dichloro Methane C. Fluorspar and Felspar D. Hydrofluosilicic Acid

Difluorodichloromethane (CFC-12) is the most common type of Freon. It is a colorless, odorless gas that is nonflammable and nontoxic. It is also very stable, which makes it ideal for use as a refrigerant.

CFC-12 is a greenhouse gas, and it contributes to climate change. It also depletes the ozone layer, which protects the Earth from harmful ultraviolet radiation.

For these reasons, the use of CFCs has been phased out. However, they are still used in some applications, such as in some medical devices.

The other options are incorrect.

• Calcium Tetra Fluoride is a white, crystalline solid that is used in the production of aluminum and other metals.
• Fluorspar and Felspar are minerals that are used in the production of glass and ceramics.
• Hydrofluosilicic Acid is a colorless, fuming liquid that is used in the production of hydrofluoric acid and other chemicals.
