प्रश्न
What kind of energy transformations take place at a coal-based thermal power station?
उत्तर
At a thermal power station, the chemical energy of coal is converted into heat energy, which is further converted into kinetic energy of fast moving steam which drives huge turbines. The turbines connected to the electric generator generates electrical energy. The energy transformation can be shown as,
Chemical energy > Heat energy > Kinetic energy > Electrical energy
