Burning coal is a chemical change. Anytime heat is released (as such in fire) it will be a chemical property 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.
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.
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.
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.
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.

No. Burning anything is 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.
For example burning of coal is 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.
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
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.
A chemical change.Coal(carbon) become CO2 or CO.Heat generation is secondary to the chemical process.
Chemical. It is called combustion.
Mining coal is a physical change because the act of extracting coal from the earth does not alter its chemical composition. The coal remains chemically the same before and after the mining process.
