Question

1.
A coal-fired power station generates electricity. Coal is burnt and the energy released is used to
boil water. The steam from the water makes the generator move and this produces electricity
Which words are used to describe the energy stored in the coal and the energy of the moving
generator?
coal
generator
A
chemical
hydroelectric
B
chemical
Kinetic
с
hydroelectric
geothermal
geothermal
Kinetic
2.​

Answer 1

Answer:

geothermal - kinetic

Explanation:

Geothermal means that heat from the Earth, so coal is Geothermal.

The moving part of the machines which are generators, its energy is kinetic

Answer 2

Answer:

The correct answer is Geothermal energy

Explanation:

Geothermal energy is the thermal strength inside the Earth's crust which originates from the formation of the planet and from radioactive decay of substances in presently uncertainly however possibly roughly equal proportions. The excessive temperature and pressure in Earth's interior purpose a few rock to melt and strong mantle to behave plastically. This consequences in elements of the mantle convecting upward considering it's miles lighter than the encircling rock. Temperatures at the core–mantle boundary can attain over 4000 °C (7200 °F).

Geothermal heating, the use of water from hot springs, as an example, has been used for bathing due to the fact that Paleolithic times and for area heating considering that ancient Roman instances. extra currently geothermal power, the term used for generation of energy from geothermal energy, has won in importance. it's miles envisioned that the earth's geothermal sources are theoretically more than adequate to deliver humanity's strength desires, despite the fact that simplest a very small fraction is currently being profitably exploited, often in regions near tectonic plate limitations.

Due to government assisted studies and enterprise revel in, the value of producing geothermal power reduced with the aid of 25% over the Nineteen Eighties and Nineties. extra recent technological advances have dramatically decreased prices and thereby accelerated the variety and length of feasible resources. In 2021, the U.S. branch of electricity estimates that geothermal strength from a strength plant "constructed today" expenses about $0.05/kWh.
