Question

why do we blow on hot potatoes​

Answer 1

Answer:

to become cool that's all

Answer 2

We blow on hot potatoes that have been just cooked because the moisture and heat present inside it doesn't disperse out that quickly.

Detailed answer

When we blow the air the pressure it creates drives away the moisture and heat that is present inside the layers of the potatoes.

• Another reason is that the air we blow is much cooler than the hot potatoes so it cools it a little bit.
• We can eat it much quickly without burning our mouth this is the basic reason.
• The water molecules present in the potatoes are in a state of gaseous-liquid state so the air we blow helps it to come into its gaseous state hence helping it to evaporate quickly.
