Q. The gas used in the Refrigerator is:

A
Argon
B
Krypton
C
Freon
D

Solution:

Modern refrigerators usually use a refrigerant called HFC-134a (1,1,1,2-Tetrafluoroethane), which does not deplete the ozone layer, instead of Freon. A R-134a is now becoming very uncommon in Europe. Newer refrigerants are being used instead.
