Question

does cold energy exist? if not, why does our A.C.'s and refrigerators and fans use electrical energy to remove or destroy the heat energy ( if they destroy the energy; wtf__I mean what happened to the law of conservation of energy!?)​

Answer 1

Answer:

yaa we can say thal cold energy exist.for example- when u cool the glass very much then it will be broken.

but about ac and refrigirator means nothing ,air (refron gasses) are compressed through a large opening of pipe and it comes out side from a small opening ,air losses its energy in the form of heat to come from a small opening. it depends on pressure of air and area of opening end of pipe
