Question

As a car runs out of petrol, what happens to the petrol?

• A. It gets converted into other compounds
• B. It gets destroyed
• C. It gets vapourized
• D. It gets leaked

Answer 1

The correct option is A It gets converted into other compounds

When petrol burns in air, it gets converted into carbon dioxide and water vapour, which come out in the exhaust of the car. The entire mass of elements present in the petrol is still intact, but they are no longer in the petrol tank. This means a chemical reaction has occured and mass is conserved.
