Question

Assertion : In a candle, wax vapors burn in sufficient supply of oxygen, which leads to blue flame.
Reason : When the oxygen supply is sufficient, then fuels burn completely producing a blue flame.

Answer 1

Answer:

both assertion and reason are correct

Answer 2

In a candle, complete combustion occurs that is indicated by a blue flame which occurs when the air or oxygen supply is sufficient due to the complete burning of fuels.

• In the situation of a sufficient amount of supply of oxygen, the fuel burns completely and a blue flame is produced in the candle because in a sufficient amount of oxygen supply the wax vapours burn completely.
• The light produced by such a blue flame is not much.
• Complete combustion occurs that is indicated by the blue flame.
• In case the air supply or oxygen supply is sufficient then a blue flame is produced because the fuel burns completely.

Hence, the assertion and reason are correct and the reason is the correct explanation of the assertion.
