Quick Answer: What is the energy transformation that takes place when coal is burned?

Chemical energy is stored in the hydrocarbon molecules in the coal. When the coal is combusted, this chemical energy is transformed into heat. (Chemical energy → Heat) The hot exhaust gases from the combustion reaction is used to heat up water into steam, which travels through pipes at high pressures and speeds.

What is the energy transformation that takes place when coal is burnt?

The burning coal heats water in a boiler, creating steam. Steam released from the boiler powers an engine called a turbine, transforming heat energy from burning coal into mechanical energy that spins the turbine engine.

How is coal transformed into energy?

Coal-fired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into water and returned to the boiler to start the process over.

Is burning coal a chemical energy?

Chemical energy is energy stored in the bonds of atoms and molecules. Batteries, biomass, petroleum, natural gas, and coal are examples of chemical energy. Chemical energy is converted to thermal energy when people burn wood in a fireplace or burn gasoline in a car’s engine.

What happens when coal is burned?

All living things—even people—are made up of carbon. But when coal burns, its carbon combines with oxygen in the air and forms carbon dioxide. Carbon dioxide (CO2) is a colorless, odorless gas, but in the atmosphere, it is one of several gases that can trap the earth’s heat.

What is the coal energy?

Coal is classified as a nonrenewable energy source because it takes millions of years to form. Coal contains the energy stored by plants that lived hundreds of millions of years ago in swampy forests. … The resulting pressure and heat turned the plants into the substance we call coal.

How is coal burned?

How coal is burned. Almost all coal plants operating today use “pulverized coal” (PC) technology, which involves grinding the coal, burning it to make steam, and running the steam through a turbine to generate electricity. … Coal combustion is the leading source of US sulfur dioxide emissions.

Which type of reaction is burning of coal?

Burning of coal undergoes combustion reaction. Combustion reaction is a type of reaction in which chemical species experiences oxidation by undergoing a reaction with the oxidizing agent which results in the emission of energy in the form of heat. It is an exothermic process.
