Question

List out the things when you need to cool by blowing

Answer 1

Answer:

When you blow on a hot drink or a food containing a lot of moisture, most of the cooling effect is due to evaporative cooling. ... Water molecules in hot foods and drinks have enough energy to escape into the air, changing from liquid water to gaseous water (water vapor).

Answer 2

The air from your mouth doesn’t become hot or cold. This means it does not have a different temperature. In fact, the air from your mouth always has the same temperature which cannot change according to your wish.
