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 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 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 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.

Which is better a coal burning barbecue grill or a gas grill?
I reccomend you get a coal burning grill. With the gas grill, sure the flavor is great. But with the coal grill, you can capture the true flavor of backyard bbq. It's a bit of a pain to handle, but the foods worth it.
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 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 mining coal a physical or chemical change?
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.
Is burning coal a reversible change?
No, burning coal is an irreversible change as it involves a chemical reaction that transforms the coal into new substances such as carbon dioxide and ash. Once coal is burned, it cannot be reverted back to its original form.
What can be a chemical change?
For example burning of coal is a chemical change.
