Question

References Liquid freon (CC12F2) is used as a refrigerant. It is circulated inside the cooling coils of older refrigerators or freezers. As it vaporizes, it absorbs heat. How much heat can be removed by 1.30 kg of Freon as it vaporizes inside the coils of a refrigerator? The heat of vaporization of Freon is 38.6 callg. Heat- cal

Answer 1

1) Given:

Heat of Vaporization of freon = 38.6 cal/gm

Mass of freon = 1.30 kg = 1.30× 1000 = 1300 GM

Since, 1gm freon removes 38.6 cal heat

So, 1300 gm freon will remove

=38.6×1300= 50180 cal heat (Answer)
