Question

Water is boiled. The resulting steam is blown again huge turbine blades. The turbine blades spin in a magnetic field, producing electricity. The electricity is used to light a lamp. Describe the energy conversions involved.

Answer 1

Step-by-step explanation:

A turbine is a mechanical device that can be used for the conversion of one form of energy into another.

The boiled water generates thermal energy which is blown against a huge turbine blades. The thermal energy is converted to mechanical energy (which drives the blades of the turbine), and sound energy in the turbine. The spinning blades thereby cut the magnetic field as they rotates inducing electric current (Fleming's left hand rule), thus electrical energy is produced.

The electrical energy is now converted to light energy and heat energy by the lamp.
