Question

coal is used for production of electricity in thermal power station. explain how energy transform from one form of energy into another form before converting into electrical energy. ​

Answer 1

coal contain chemical energy when it is heated at high temperature the heat is released and it is used for burning of water then the steam of high pressure and temperature is created which rotates the magnet in generator.

energy flow----

chemical energy in coal ---heat energy ---kinetic energy in steam ----electrical energy

Answer 2

in thermal power , heat energy ( coal) ---> kinetic energy ( steam ) ----> mechanical energy ( turbine)----> electrical energy

in hydroelectric power,, kinetic energy (of water) ----> mechanical energy ( turbine )

----> electrical energy
