How does energy changes from one form to another in a coalburning power plant?

A power plant works like a heat engine. It receives thermal energy as heat and transforms part of it to mechanical energy discarding the rest as heat to the surroundings.
In a coal burning power plant, the coal's chemical energy is liberated as heat and
used to generate steam (at the steam generators) at high temperature and pressure.
This high energy steam (large enthalpy content) is fed to steam turbines that are coupled to large electricity generators responsible of the plant's electric power output. The exhausted steam (at lower temperature and pressure) is sent to condensers which cool down the steam flow to get a flow of cool liquid water (The condensers require cold water to condense the steam)*. The cool condensed water flow is sent to a pump to lift its pressure high enough to be introduced to the heating system equipment (steam generators). The working fluid (water) has run a
a full cycle.
*The plant requires a "heat sink", a cooling source for the condensers cooling water. That is why power plants are constructed by a river or by the sea. If that
is not an option, cooling towers are required.

What process converts the suns energy into sugars?
In a plant, the process is called Photosynthesis. It is when the plant absorbs the sun's energy and makes G3P, a sugar that is made into Glucose- another sugar.
How does the transformation of energy take place in hydropower plant station?
The transformation of energy take place in hydropower plant includes:Potential energy -> kinetic energy-> electrical energy
Describe the energy changes that occur during photosynthesis?
the plant organism cover the sun energy into chemical energy
What is the energy transformation in the solar power plant?
solar (photovoltaic) power plant > radiant energy from the sun > converted to electrical energy
How does gravity change water potential energy?
Take for example a dam, and the process which electricity is produced from water by gravitational force. When water rushes down the penstock into the turbine, it creates a rotational energy. The rotational energy is transfered to the spindle. At which point the spindle passes its energy off to an alternator. The alternator will create electricity. Thus, when you take gravity into account, water is a great potential energy. You need little to no fossil fuels to sometimes create more energy than a power plant. Simple and sweet too, I might have missed a couple key concepts
Can a turbine in a hydroelectric power plant makes energy?
Well, no. A turbine does not MAKE energy. It changes one form of energy to another. A Pelton turbine in a hydroelectric plant changes the weight and force of falling water to rotary mechanical energy, which is used to turn a generator. That changes mechanical energy to electrical energy. But none of that MAKES energy.
The plant structure that changes light energy to chemical energy is a?
chikala
What chemical changes light energy into chemical energy in a plant?
hi
What happens to energy from the sun during photosythesis?
it changes into chemical energy by plant
A hydroelectric power plant changes the energy of moving water into?
crackheads
What changes energy into food in plant cells?
Glycolysis is the process that converts the energy stored in food into a form that cells can use. It takes sugar from food and breaks it down through the mitochondria to make ATP.
Is photosynthesis an energy releasing process?
Yes, and no. It is when the plant takes in sunlight, and changes it in to energy, so it gains energy, and releases oxygen.
A what is a device that changes kinetic energy into electrical energy?
A generator in a power plant converts rotating kinetic energy into electrical energy An electric motor is a device which changes electrical energy into kinetic. For example-- Fans could be like electric energy to kinetic energy...
How does plant obtain food?
by taking its nutriants from another plant
How is energy converted by plans during the process of photosynthesis?
The light energy from the sun changes into chemical energy (Sugar) which the plant feeds off along with water.
What is the definition of energy transformations?
2. Energy can change from one form to another. This is called an energy conversion or energy transformation. • The Law of Conservation of Energy states that energy can change form, but it cannot be created or destroyed. Therefore, the total amount of energy stays the same. • In energy transformations, some energy is always lost to the environment as thermal energy. Examples of energy transformations and their uses: · A television changes electrical energy into sound and light energy. · A toaster changes electrical energy into thermal energy and light. · A car changes chemical energy from fuel into thermal energy and mechanical energy. · A flashlight changes chemical energy from batteries into light energy. · Solar energy is converted into electrical energy using solar panels. · Campfires convert chemical energy stored in wood into thermal energy, which is useful for cooking food and staying warm.
Which type of organism changes energy from sun into food for itself and others?
the answer you are most likely looking for is any photosynthetic plant.
