Which of the following is the energy transformation in a geothermal power plant?
Water or working fluid is heated (or used directly incase of geothermal dry steam power plants), and then sent through a steam turbine where the thermal energy (heat) is converted to electricity with a generator through a phenomenon called electromagnetic induction.
How is geothermal energy converted into kinetic energy?
A geothermal power plant drills wells into a reservoir and uses either the steam or hot water from within the Earth to generate energy. … Steam makes the large blades of the turbine spin, transforming heat energy into kinetic energy.
How heat transfer and energy transformation make geothermal plants work?
They work by piping hot steam from underground reservoirs directly into turbines from geothermal reservoirs, which power the generators to provide electricity. After powering the turbines, the steam condenses into water and is piped back into the earth via the injection well. … The steam produced powers the turbines.
Which of the following devices is used in a geothermal power plant?
The turbine and generator are the primary pieces of equipment used to convert geothermal energy to electrical energy.
What is geothermal energy short answer?
Geothermal energy is the heat that comes from the sub-surface of the earth. It is contained in the rocks and fluids beneath the earth’s crust and can be found as far down to the earth’s hot molten rock, magma. … There are three types of geothermal power plants; dry steam, flash and binary.
Is geothermal energy potential or kinetic energy?
|type||motion||examples and subtypes|
|thermal energy||random motion of microscopic particles of matter (molecules, atoms, ions)||heat, fire, geothermal, …|
|electrical energy||bulk flow of charges (electrons, protons, ions)||household current, AC and DC circuits, lightning, …|
What are the two ways in which geothermal energy is generated?
Magma heats nearby rocks and underground aquifers. Hot water can be released through geysers, hot springs, steam vents, underwater hydrothermal vents, and mud pots. These are all sources of geothermal energy. Their heat can be captured and used directly for heat, or their steam can be used to generate electricity.
