Question

HELP!!!!!!!!

Answer 1

Answer:

Mechanical

Explanation:

"Steam from the boiler spins the blades of an engine called a turbine, transforming heat energy from burning coal into mechanical energy that spins the turbine engine. 5. The spinning turbine is used to power a generator, a machine that turns mechanical energy into electric energy."

Answer 2

Answer:

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.
