Question

Liquid freon, CCl2F2 is used asa refrigerant. It is sirculated inside the cooling coils of arefrigerator or freezer. As it vaporizes, it absorbs heat. How muchheat could be removed by 2.21kg od freon as it vaporizes inside tecoild of a refrigerator? The heat of vaporization of freon is162J/g. If some one could please do this problem. I did itand would just like to check my answer!

Explanation / Answer

Given that Mass of freon = 2.21 kg = 2210 g Heat of vaporizationof  CCl2F2 = 162J/g    The amount heat required to vaporize 2210 g offreon = 2210 g * 162 J/g                                                                                      =358020 J                                                                                     = 358.02 kJ Hence 358.02 kJ heat could be removedby 2.21kg od freon as it vaporizes. Hence 358.02 kJ heat could be removedby 2.21kg od freon as it vaporizes.
