Solution

Keep your palm in front of the mouth and blow some air. It will feel warm. This proves that the air that is breathed out is warmer. In place of the hand, we can also place a folded handkerchief, we can feel that the place where we breathe out is warmer than the area which was not in contact with your breathe.
