Given:
Coal-fired power plant
Required:
Energy transformation in coal-fired power plant.
Step-by-step explanation:
Coal has chemical energy.
When the coal is heated, the chemical energy transforms into thermal energy.
Thermal energy is used to rotate the blade of the turbine, so thermal energy transforms into mechanical energy.
The rotating blades produce electricity, so mechanical energy transforms into electrical energy.
Final Answer: The energy transformation of a coal-fired power plant is chemical to thermal to mechanical to electrical.
