Question

Put your hand at some distance from your mouth and blow again does the air from your mouth feel warm why

Answer 1

no becoz d air from our mouth can't reach that much far where or hand is

Answer 2

if it is at a less distance than our hand will feel warm because our body temperature is more than that of our surroundings and if it is at more distance it will not fill anything because air will not reach up to that distance.
