Question
Explain with diagram step-by-step energy conversion in Thermal power plant
Solution
Water is heated in a boiler. Using the thermal energy released due to burning of coal, steam of very high temperature and pressure
is generated. The energy in the steam drives the turbine. Thus, the generator connected to the turbine rotates and electrical energy is produced.
Chemical energy in coal → Thermal energy → Kinetic energy in steam→ kinetic energy
