Answer:
1)Fuel efficiency is measured as the amount of heat that 1 kg of fuel (any fuel) produces on combustion. ... This is known as the calorific value of the fuel. The unit of measurement of fuel efficiency is kilojoules per kg, i.e. kJ/kg.
2)Flame of burning candle goes off when we blow strongly over it because burning of a substance and production of energy from it is called as combustion and it is a gas phase reaction.
