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 in a furnace a chemical change?
Yes, burning coal in a furnace is a chemical change. During combustion, the coal undergoes a chemical reaction with oxygen to produce heat, carbon dioxide, and other byproducts, resulting in a change in the chemical composition of the coal.
Is burning coal for a barbecue physical or chemical change?
Burning coal for a barbecue is a chemical change because the coal undergoes a chemical reaction with oxygen in the air to produce heat and light, along with byproducts like carbon dioxide and ash.
Is Burning coal physical or chemical change?
Burning coal is a chemical change because it involves a chemical reaction where the coal combines with oxygen to produce new substances like carbon dioxide, heat, and ash. This process results in the formation of different molecules with different properties from the original coal.
Is burning of coal a chemical change?
Yes, burning coal is a chemical change. During this process, the coal undergoes a chemical reaction with oxygen in the air to produce heat, carbon dioxide, and other byproducts. This results in a new substance being formed, indicating a chemical change.

Is burning coal for a barbecue a physical change?
Yes, burning coal for a barbecue is a chemical change. This is because the combustion process results in a chemical reaction where the coal combines with oxygen to produce heat, carbon dioxide, and other byproducts.
What is the energy change in burning coal?
The energy change in burning coal is a chemical reaction in which the potential energy stored in the chemical bonds of coal is converted into heat and light energy. This process releases heat and other byproducts, such as carbon dioxide and sulfur dioxide, into the atmosphere.
Why is burning of coal a chemical change?
Burning coal is a chemical change because it involves a reaction between the coal (a hydrocarbon) and oxygen in the air to produce heat, light, and carbon dioxide. This reaction results in the formation of new substances, indicating a chemical change.
Is burning coal an exothermic chemical reaction?
Yes, burning coal is exothermic, in fact, that is why people burn coal. It produces heat.
Is a lump of coal burning a physical change?
A chemical change.Coal(carbon) become CO2 or CO.Heat generation is secondary to the chemical process.
How could a person change the stored energy in a lump of coal into chemical enegry?
A person could change the stored energy in a lump of coal into chemical energy by burning the coal. Combustion of coal involves a chemical reaction that releases the stored energy in the form of heat and light energy.
Would burning coal in a furnace result in a chemical change?
Yes. Some of the coal is being converted into heat energy, water, and a carbon compound. This is known as a combustion reaction.
