Question:

In a refrigerator what produces the cooling ?

Options:
A) The ice which deposits on the freezer
B) The sudden expansion of a compressed gas
C)

The evaporation of a volatile liquid

D) None of these
Solution:
Ans:(d) None of these


 The reason is the hot temperature is TAKEN OUT by low boiling temperature of the refrigerant. Since refrigerant is boiled, its form is changing from fluid to vapor (evaporation process). Since hot temperature is taken away, the cooling effect is occured.
