Solution
The correct option is A Scene 1
When we put our hands at some distance from the mouth and blow on them, the warmth experienced is less. This is because while travelling from mouth to our hands, the air from mouth gets mixed with the outside air and becomes cool. Thus, more warmth is experienced in scene 1.
