Coal is burned as fuel to heat water in a boiler, producing steam. The steam drives a turbine, which is connected to an electric generator. In which order do the major energy transformations take place?

Achemical energy → heat energy → electrical energy → kinetic energy

Bchemical energy → heat energy → kinetic energy → electrical energy

Cheat energy → chemical energy → electrical energy → kinetic energy

Dheat energy → chemical energy → kinetic energy → electrical energy

✓ Correct answer

B: chemical energy → heat energy → kinetic energy → electrical energy
