Question

Q4. A corn-seller (Bhuttewalah) fans the coal when he prepares the corn. Why?​

Answer 1

Answer:

Why does a popcorn seller blow on the burning pieces of coal?

Burning coal requires oxygen to chemically react (C+O2=CO2). The availability of oxygen is limited in the furnace by several factors such as the friction of the air against the coal. Blowing provides more oxygen to the flame and raises the temperature of the flame. The hotter flame pops the corn more rapidly. Blacksmiths use the same principle to raise the temperature of their forges.

Answer 2

Question hidden with physics!

A corn-seller fabs the coal when he prepares the corn this is because providing air to the burning coal receives oxygen from the environment and thus oxygen is a supporter of combustion and hence the flame increases and the corn is prepared much early and easily.
