Question

Between steps 4 and 5, the mechanical energy of the turbine is converted to

Answer 1

Answer:

electrical energy

Explanation:

The Sun is involved in the formation of most of the energy sources on Earth. It is even involved in the formation of fossil fuels. Thus, the Sun is the ultimate source of energy for any energies derived from the fossil fuels.

Fossil fuels are made when plants use solar energy to make chemical energy in the form of sugar. When the plants die, they are compressed and form coal.

When the coal is burned, the chemical energy in the coal is converted into heat energy which is used to make steam. The steam causes a turbine (i.e., a very large fan blade) to turn thus producing mechanical energy. As the turbine turns, electrical energy is generated which can then be transmitted through power lines.

Answer 2

Answer:

Between steps 4 and 5, the mechanical energy of the turbine is converted to electrical energy.

Explanation:

A turbine can be described as rotating device which converts energy from fluid like water or energy from the wind into useful form of energy like electricity.

There are different types of turbines each made to generate energy from different sources.

To generate hydroelectricity, the water which is stored in a dam (potential energy) is released over a rotating turbine (mechanical energy) made of blades which converts it into electrical energy.
