Hi all, I actually work in physics (quantum physics) but my thermodynamics knowledge is a bit lacking these days. The following problem has had me puzzled for quite a long time. Basically, if I point the hot air coming out of a hairdryer at a target, will that target's temperature ever go higher than the temperature of the hot air? I recall reading somewhere that hairdryers product air at 60 degrees C, which is just below the threshold that can cause burning. Thanks.
