Answer:
The correct answer is -
Thermal, mechanical, electrical, and thermal.
Explanation:
In this system, From the flames, two types of energy generate light and thermal, thermal energy heats the other object while light energy only provides light so the kettle gets heat from thermal energy.
Thermal energy from flames converts water into steam which in turn moves out of the kettle and turns the turbine by mechanical energy to produce electrical energy. The electrical energy increases the temperature of water and produces steams and it release in the atmosphere in the form of thermal energy.
