What energy of coal is released as it burns?
chemical energy into heat energy
Why are coal fires inefficient?
Because a lot of the energy used to hear up the room is lost to the surroundings eg for every 100 J of energy stored in coal and released as heat about 25 J is used to heat u the room whilst the rest is lost to the surroundings
What type of coal burns the most effeciently?
The type of coal that burns the most efficiently is anthracite coal.
Which burns hottest coal or wood?
Coal
How energy can be produced from coal?
Coal burns. The heat boils water. The steam is used to push a turbine. The turbine rotates a generator (its a trick with magnets) that produces the electricity.
What energy of coal is released as it burns?
chemical energy into heat energy
What energy transfers happen when coal is turned in to electric?
when coal burns the energy change is chemical -------------> electrical
When coal burns what forms of energy are released?
light and heat energy
Is energy wasted in a coal - fired power plant?
Chemical energy is released when the coal burns with oxygen in the air. This energy is used to heat water, which is converted into steam. Not all of the energy is used to heat the water. Some of it is wasted by being transferred as heat to the surroundings. The energy of the steam is used to turn the turbines, but some of the steam energy is wasted.
What is a substance that can burns in order to produce heat or energy?
coal
Why is coal used for electricity?
When coal burns, it produces heat. This can be converted to other forms of energy.
What happens when fuel such as coal or gasoline burns?
we release the potential energy to heat energy to do work
What is a coal-fired energy plant?
A coal-fired energy plant is one that burns coal (as the source of energy) to make electricity or drive machinery.
What is useful energy transfer when coal is burnt?
Chemical energy is transferred to electrical energy! :) :p
Which type of coal burns long but dos not provide lots of energy?
Lignite.
What is the useful energy transfer when coal is burnt?
Chemical energy is transferred to electrical energy! :) :p
Does coal have thermal energy?
Coal by itself lacks thermal energy, apart from what is given to it by its surroundings (e.g. the Earth--which gives everything on its surface thermal energy--warm air, or other nearby sources of heat).
