Question

Before you go for a long drive in your car, your father fills the tank with the required fuel. The fuel flows into the engine and burns with oxygen. This gives energy to the car to move forward. (i) What energy is contained in the fuel? (ii) While the fuel burns, what energy conversion takes place? (iii) What energy is responsible for the movement of the car?​

Answer 1

Answer:

(i)-Chemical energy

(ii) chemical energy becomes heat energy

iii - Mechanical energy

Explanation:

Fuels like petrol or diesel are fossil fuels.They are made of chemical compounds that underwent high pressures for a long period of time.

in a fossil fuel engine the chemical energy is used to creat heat energy , then the heat energy is used to push pistons.

Please note that this type of energy conversion does not happen in a electric car.the chemical energy stored in the battery is converted to electrical energy and then mechanical.

another plus point when the number of conversions increase the amount of the waste of energy increase
