A hydroelectric dam converts the potential energy stored in a water reservoir behind a dam to mechanical energy—mechanical energy is also known as kinetic energy. As the water flows down through the dam its kinetic energy is used to turn a turbine.
What is the energy transformation that best describes how a hydroelectric plant works quizlet?
Hydroelectric power converts energy (from flowing water) into energy (electricity). Potential energy in settled water turns into kinetic energy when it starts to flow down. Kinetic energy turns into mechanical energy when the flowing water has entered the turbines.
What kind of energy transformation takes place at a hydroelectric power station?
“A hydraulic turbine converts the energy of flowing water into mechanical energy. A hydroelectric generator converts this mechanical energy into electricity.
How do energy transformations occur in a hydroelectric plant quizlet?
What energy transformations occur in a hydroelectric plant? The kinetic energy of the moving water is transformed to electric energy. The kinetic energy of the moving water turns turbines, allowing a generator to convert the kinetic energy into electrical energy.
Which describes this energy transformation from the turning turbine to electricity?
Mechanical energy from the turbine is converted to electric energy in the generator. Electric energy from the generator is converted to chemical energy in the power lines.
How is hydroelectric energy created quizlet?
Also known as hydroelectricity; a form of energy generated by the conversion of free-falling water to electricity. Electricity is generated using the motive power of water. The volume of water flowing through a river channel. … The resulting reservoir is used in the generation of electricity or as a water supply.
What occurs during an energy transformation?
Energy transformation, also known as energy conversion, is the process of changing energy from one form to another. … For example, to heat a home, the furnace burns fuel, whose chemical potential energy is converted into thermal energy, which is then transferred to the home’s air to raise its temperature.
How does hydroelectric energy work?
Hydroelectric power is produced with moving water
At hydropower plants water flows through a pipe, or penstock, then pushes against and turns blades in a turbine to spin a generator to produce electricity. … Most U.S. hydropower facilities have dams and storage reservoirs.
What is hydroelectric energy and what type of energy does it produce?
Hydropower utilizes turbines and generators to convert that kinetic energy into electricity, which is then fed into the electrical grid to power homes, businesses, and industries.
Which of the following explains the energy transformation in a hydroelectric power plant like the Buford dam?
Explanation: The hydropower stations uses the energy from the falling water from the river or dam to generate electricity. The kinetic energy of the waves of water is used to move the turbine. This way the kinetic energy of water is converted into mechanical energy.
Which list gives the proper sequence of energy changes that occur in a hydroelectric plant?
This final process is mechanical energy converted into electrical energy. So, from this we can conclude that the correct sequence in a hydroelectric power station is kinetic energy converted to potential, which is later converted to mechanical energy.
Which best describes how energy changes form?
Which best describes how energy changes form in a car’s engine? A single transformation occurs because the chemical energy of the fuel is changed to the mechanical energy of the car. … Multiple transformations occur because the chemical energy of the fuel is changed to several forms of energy.
How are geothermal and hydroelectric energy similar?
Geothermal and hydroelectric are renewable sources of energies and produce “clean” fuel sources. Geothermal energy is heat stored deep inside the earth or occasionally in hot springs. … Hydroelectricity is a form of energy generated by the motion of water (kinetic energy) and is converted into electricity.
What energy transformations occur in a wind turbine?
A wind turbine transforms the mechanical energy of wind into electrical energy. A turbine takes the kinetic energy of a moving fluid, air in this case, and converts it to a rotary motion. As wind moves past the blades of a wind turbine, it moves or rotates the blades.
How is energy transformed into electricity?
Electrical energy is caused by moving electric charges called electrons. Electricity is a type of energy that comes from electrical energy. … In power stations, turbines are turned using energy from sources such as heat, wind and moving water. Generators are machines for converting motion energy into electricity.
Which of the following best describes the energy transformations that occur in a toaster?
Electrical energy is transformed into thermal energy in the toaster, and chemical energy is transformed into thermal energy in the toast.
