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.

During photosynthesis what happens to energy?
During photosynthesis, energy from sunlight is captured by chlorophyll molecules in plant cells. This energy is then used to convert carbon dioxide and water into glucose (a form of chemical energy) and oxygen. The glucose can be used by the plant for energy or stored for later use.
What happens in an energy source?
In an energy source, such as a power plant or a battery, energy is converted from one form to another. For example, in a power plant, mechanical energy from a turbine is converted into electrical energy. In a battery, chemical energy is converted into electrical energy.
How does the law of conservation of energy apply to the coal power plant?
The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another. In a coal power plant, the energy stored in coal is converted into thermal energy through combustion, which is then used to generate electricity. This process abides by the principle of conservation of energy.
When energy is used it is?
converted from one form to another. For example, when electricity is generated in a power plant, the chemical energy in the fuel is converted to electrical energy. Similarly, when you consume food, the chemical energy stored in the food is converted to mechanical energy for your body to use.
What uses energy and can create energy?
A power plant or generator can create energy by converting one form of energy into another. Energy-consuming devices like appliances, machines, and vehicles use energy to perform tasks or operations.
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 happens to energy from the sun during photosythesis?
it changes into chemical energy by plant
During photosynthesis what happens to energy?
During photosynthesis, energy from sunlight is captured by chlorophyll molecules in plant cells. This energy is then used to convert carbon dioxide and water into glucose (a form of chemical energy) and oxygen. The glucose can be used by the plant for energy or stored for later use.
A hydroelectric power plant changes the energy of moving water into?
crackheads
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.
How does plant obtain food?
by taking its nutriants from another plant
What changes energy into food in plant cells?
Photosynthesis is the process by which plant cells convert light energy into chemical energy in the form of glucose (food). This process occurs in the chloroplasts of plant cells, where chlorophyll absorbs light energy, which is then used to convert carbon dioxide and water into glucose and 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...
What is the process that changes light energy to chemical energy?
The process that changes light energy to chemical energy is called photosynthesis. It occurs in the chloroplasts of plant cells, where specialized pigments capture light energy and convert it into chemical energy in the form of glucose. This chemical energy is then used by the plant for growth, maintenance, and reproduction.
What happens in an energy source?
In an energy source, such as a power plant or a battery, energy is converted from one form to another. For example, in a power plant, mechanical energy from a turbine is converted into electrical energy. In a battery, chemical energy is converted into electrical energy.
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.
