Show answer
Answer: (3) Refrigerant
సమాధానం: (3) శీతలకరణి
Chlorofluorocarbons (CFCs, e.g. Freon) were widely used as refrigerants in refrigerators and air conditioners; they deplete the ozone layer and are being phased out under the Montreal Protocol. Aerated drinks contain dissolved carbon dioxide, not CFCs.
