Why is fire round if there is no force of gravity ?

Why is fire round if there is no force of gravity ?
by

1 Answer

Answer :

The force of gravity means that if there was no pull of the earth, the shape of the flame of fire would be round! If there was a force of gravity, the air near the flame would heat up and light air would rise. But since there is no force of gravity, the air around the flame, whether it is light or heavy, cannot move. As a result, the flame became round and burned due to the surrounding wind. And if all the surrounding oxygen was burned, it would go out on its own.

(4) water and petrol are immiscible with each other and petrol which forms the upper layer continues to burn Explanation: Water is not effective in extinguishing a fire caused by petrol because water and petrol are immiscible with each other and petrol which forms the upper layer continues to burn. The specific gravity (or relative density) of gasoline ranges from 0.71-0.77 kg/l (719.7 kg/m3) while the specific gravity of water is 1000 kg/m3 and that is why gasoline or petrol floats on the upper surface of the water. Water cannot generally be used to extinguish a gasoline fire, unless used in a fine mist.
