In a natural gas power plant, natural gas is burned to heat steam, which turns a turbine. What energy conversion is happening in
a natural gas power plant? A. Chemical energy to heat energy to kinetic energy to electrical energy. B. Nuclear energy to heat energy to kinetic energy to electrical energy. C. Electrical energy to chemical energy to kinetic energy to heat energy D. Heat energy to chemical energy to electrical energy to kinetic energy.
The answer is A. Chemical energy to heat energy to kinetic energy to electrical energy.
<h2>Why?</h2>
Let's check the energy conversion given in the statement:
Chemical energy: Chemical energy is usually obtained from a natural resource combustion. For this particular case is the result of natural gas combustion.
Heat energy: Heat energy comes from chemical reactions such as natural gas combustions.
Kinetic energy: Kinetic energy is obtained by turbines transforming the pressurized steam on mechanical movement. Turbines are formed by a turbine that absorbs the heat energy to do mechanical work and transmit it to an output rotating shaft.
Electrical energy: Electrical energy is generated by gas turbines when the rotating output shaft is connected to an electrical generator. Electrical generators use mechanical energy to generate electrical energy by using electromagnetic induction. Electrical generators are basically formed by a rotor and a stator.
A. Chemical energy to heat energy to kinetic energy to electrical energy.
Explanation:
Chemical energy is a type of energy that is stored in all materials with chemical bonds and is released from the breakdown of these bonds. An example of chemical energy is those reactions that release or absorb heat from the environment. For this reason, we can conclude that in a natural gas plant, when natural gas is burned to heat steam, we have an example of chemical energy.
Kinetic energy is the energy associated with the movement of bodies. From Greek the term "kinetic" means "movement". Any moving body is capable of doing work, so it has energy, which in this case is called kinetics. For this reason, we can conclude that when natural gas is burned to heat the steam that transforms a turbine, we have an example of kinetic energy, since the heat of chemical energy is what causes the turbine to move.
Features. A tornado is a swirling vortex or column of air with a hollow core. The circulating air often contains debris and dust and moves in an upward spiral at high speeds. The bottom of the tornado column makes contact with the ground, while the top of the tornado can extend 5 or more miles into the sky.
