Of course they will. My hands will cool whether we touch or not.

But it is not cold that my hands absorb. There is no such thing as
cold. It is the cold radiation from your hands which will cool mine.

But it is obvious to me now that you are taking sides against me. But
tell me which of the two choices you believe is correct.


We are not 'taking sides', we are just trying to point you in the

Paul H. The second law of dynamics is bidirectional. You have never seen a cup of coffee warm up but you also have never seen an ice cube cool down. They always do warm up and melt. Heat flows to achieve and equilibrium not only towards cold.
