Q3. How does a thermal power plant work ?
Ans. 
A thermal power plant generates electricity by converting heat energy into electrical energy.
• Fuel (such as coal, natural gas, or oil) is burned to produce heat

• The heat is used to boil water and produce steam

• The steam drives a turbine connected to a generator, which produces electricity

• The electricity is then transmitted through power lines to homes and businesses
