Bituminous coal is changed by heat and pressure into the metamorphic rock anthracite.
When coal is burned, chemical energy stored in the coal is converted into heat energy. This heat energy is then used to produce steam, which drives turbines to generate electricity.
When coal is burning, chemical energy stored in the coal is converted into heat energy and light energy. The heat energy is used to generate steam that drives turbines, which then converts the energy into electrical energy.
the coal is designed to absorb heat at when heat hits it it stores that heat ++++ No. The energy is stored by coal simply being a combustible material, so it contains potential chemical energy.
When coal is burned, stored energy is released in the form of heat. This heat is typically used to generate electricity by heating water to produce steam, which drives turbines connected to generators.
When coal is burned to make steam, the stored chemical energy in the coal is released as heat energy through a combustion reaction. This heat energy is then used to heat water and produce steam, which in turn drives turbines to generate electricity. The thermal energy from burning coal is transformed into mechanical energy and then electrical energy in this process.
Coal is a fossil fuel,that is being used to produce electricity and heat.
Not sure if this will answer your question, but I'll give it a shot. It's less about the fact that is is coal and more about the fact that coal gives off heat. When coal was first being used as a heat source, it was cheaper than wood and there was a lot of it. So really the origin of the energy is in the heat that the coal generates when on fire and less about the coal itself.

They burn it. It's the heat and expanding gases from the coal being burned which provides the energy.
No. Coal is the result of organic material, primarily plant matter from bogs, being chemically altered by heat and pressure, leaving being mostly carbon.

Hmmmm, not sure. It could be coal, oil, or natural gas. But since hydro generates electricity and coal makes heat and electricity, so I think its coal.

It can in coal/wood stoves.
coal in Zimbabwe is used for many reasons. Some of them being heat (although that is not needed much in Zimbabwe) and most of it for electrical power in Zimbabwe.
