Paper is cellulose and composed of C, H, O. Product of combustion is water and carbon dioxide. Heat of formation of carbon dioxide is lower than water hence more energy release from reaction. The oxygen in it,s structure is readily to bond with carbon or hydrogen thus lesser energy available for release. When compare paper to coal which is mostly C-C bond and most product is CO2 energy available in coal is much higher. General figure for heat ofvcombustion is comparing 28.5 kJ/kg lignite to 15.8 kJ/kg paper.
What else can I help you with?
What energy does burning coal give?
Burning coal gives heat (thermal), light and sound energy.
What is burning coal?
Burning coal refers to the process of combusting coal to produce heat energy, which is often used to generate electricity in power plants. During combustion, the carbon in coal reacts with oxygen to produce carbon dioxide and release heat energy. However, burning coal also releases pollutants and greenhouse gases into the atmosphere, contributing to air pollution and climate change.
Why coal does not produce Flame?
Coal does not produce a visible flame because it needs a high amount of heat to ignite and burn. When coal is heated, it first releases volatile gases which can be lit to produce a flame. The coal itself then burns with a red glow due to the heat generated from the burning gases.
Is burning coal for heat a chemical change?
Yes, it is an exothermic chemical reaction.
Is burning of coal a physical change?
Burning of coal is a chemical change, not a physical change. During the burning process, the chemical composition of coal changes as it reacts with oxygen to produce heat, light, and ash.

What energy transformation occurs first in coal burning plants?
In coal burning plants, the first energy transformation that occurs is the combustion of coal to produce heat energy. This heat energy is then used to generate steam, which drives a turbine connected to a generator to produce electricity.
In most energy conversions such as burning coal to produce heat?
In most energy conversions, such as burning coal to produce heat, energy is transformed from one form to another. In this process, the chemical energy stored in coal is converted into heat energy through combustion. This heat energy can then be used to generate electricity or for other purposes.

Is burning coal for heat a chemical change?
Yes, it is an exothermic chemical reaction.
How renewable and non-renewable enerygy sources produce electricity?
They produce electricity be burning coal and then the coal is used to heat, light and do lots of other things.
Is burning of coal a physical change?
Burning of coal is a chemical change, not a physical change. During the burning process, the chemical composition of coal changes as it reacts with oxygen to produce heat, light, and ash.
Is burning coal mechanical energy?
No, burning coal does not involve mechanical energy. When coal is burned, it undergoes a chemical reaction to produce heat, which can then be used to generate mechanical energy through processes like steam turbine systems.
What energy can be released during the burning of coal?
During the burning of coal, chemical energy stored in the coal is converted into thermal energy in the form of heat. This heat energy can be used to generate steam, which in turn drives turbines to produce electricity.
How is the energy transferred for coal?
Energy from burning coal is transferred in the form of heat. When coal is burned, it releases energy in the form of heat that can be used to generate steam which in turn drives turbines to produce electricity.
What can a burning coal do for a power palnt?
Burning coals release heat. The heat is used to voil water to mke st4eam under pressure. This pressurised steam drives a turbine, which in turn roates a magnet in a coil to produce electricity. So over all it is thermasl energy changing into electrical energy.
