Q1. How a Thermal plant works?
Ans. 
A thermal plant works by converting heat energy into electrical energy through the use of steam turbines.
• Fuel (such as coal, natural gas, or nuclear fuel) is burned to produce heat

• The heat is used to boil water and produce steam

• The steam turns a turbine connected to a generator, producing electricity

• The electricity is then sent to the grid for distribution

• Cooling systems are used to condense the steam back into water f
