How is coal obtained?
Coal is obtained through mining. It is typically extracted from underground mines using various methods such as longwall mining or room and pillar mining. Once the coal is extracted, it is processed and prepared for use as a source of energy.
How much energy can be obtained by burning coal?
An average energy density of coal is about 24 megajoules per kilogram. This is the equivalent of about 6.67 kW·h of energy per kilogram of coal, However with the various energy transformations in the power plant (coal to heat, heat to steam, steam to mechanical movement of the turbines) and the loss of heat to the air water and solid waste less than 30% of that will become electricity. Lines losses and user losses will reduce this even further if end user available power is calculated.
Energy obtained by breaking up 1 kg of uranium is equal to the energy obtained from burning threee million kg of coal?
True. The energy released by breaking up 1 kg of uranium (in a nuclear reaction) is equivalent to the energy released by burning approximately 3 million kg of coal (in a combustion reaction). This demonstrates the much higher energy density of nuclear reactions compared to traditional fossil fuel combustion.
What types of energy are in coal?
The main types of energy in coal are chemical energy, which is released when coal is burned, and potential energy stored within the coal itself. When coal is burned, the chemical energy is converted into thermal energy, which can be used for generating electricity or heating.
What is coal energy?
Coal energy refers to the use of coal as a fuel source to generate heat or electricity. This involves burning coal to produce steam, which then drives turbines to generate electricity. However, coal energy is associated with environmental pollution and greenhouse gas emissions.
. Which is not an energy resource obtained from the ocean?
Coal.
How is coal obtained?

What source provides most of the energy for industrial production?
this energy is obtained through burning fossil fuels, coal, oil,and natural gas

How much coal has to be burned to equal the potential energy obtained by breaking one pellet of uranium?
Depends on the size of your pellet. 1 kg of Uranium235 is equivalent to 1500 tonnes of coal.
Energy obtained by breaking up 1 kg of uranium is equal to the energy obtained from burning threee million kg of coal?
True. The energy released by breaking up 1 kg of uranium (in a nuclear reaction) is equivalent to the energy released by burning approximately 3 million kg of coal (in a combustion reaction). This demonstrates the much higher energy density of nuclear reactions compared to traditional fossil fuel combustion.
What does obtained mean when talking about energy?
"Obtained" in the context of energy typically refers to acquiring energy from a source, such as solar panels obtaining energy from the sun or a power plant obtaining energy from fuel sources like coal or natural gas. It implies gaining access to and harnessing energy for various uses.
