a. Thermal power plant. Answer: In thermal power plant the turbines are rotated using steam. Here the coal is burnt. The heat energy liberated from this burning is used to heat the water in the boiler. This water produces steam of very high temperature and pressure. The kinetic energy in the steam rotates the turbines.

Condenser. Condenser is a device which condenses the exhausted steam from the turbine. The condenser serves two important functions −. It creates a very low pressure at the exhaust of the turbine, hence permitting expansion of steam in the turbine to a very low pressure. This helps in converting the steam energy into the mechanical energy.
