Combusting coal is both a chemical and a physical change.
Chemically, the main substance released in carbon dioxide. There are various other substances released in smaller quantities viz. Cabron, Carbon Monoxide, Ammonia, Hydrogen sulphide. etc.,
Physically, the energy release is 'HEAT',, but also a low degree of light (flames).
What else can I help you with?
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 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 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.
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 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 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 a physical change?
No. Burning anything is a chemical change.
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 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.
What can be a chemical change?
For example burning of coal is a chemical change.
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.
How is an chemical change differs from a physical change?
Physical change is the change in which only physical properties changes ,like color, hardness, density etc. Chemical changes affect the composition as well as chemical properties of matter and result in formation of new substance. Examples of chemical changes are : Burning of coal Burning of Paper Electrolysis of water
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.
Is breaking coal into pieces chemical or physical change?
Breaking coal into pieces is a physical change because it does not alter the chemical composition of the coal. The coal remains composed of the same elements before and after being broken into pieces.
Is burning coal an example of a physical reaction or a chemical reaction?
Chemical. It is called combustion.
