Answer
chemical to heat to mechanical to electrical.
Reason — A thermal power station is a type of power station in which heat energy is converted to electrical energy.
Here, the chemical energy of coal is changed into heat energy, which is transferred to steam. Then the heat energy of steam changes into mechanical energy of turbine that is further changed into electrical energy.
