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 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 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 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.

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 a physical change?
No. Burning anything is a chemical change.
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.
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.

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 for heat a chemical change?
Yes, it is an exothermic chemical reaction.
Which of the following will result in a chemical change A melting ice to obtain water B evaporating alcohol into vapor C drying wood in a shed D burning coal in a furnace?
The answer is D ! (a) melting ice to obtain water - is changing waterfrom its solid form to liquid by heat. (b) evaporating alcohol into vapour - is changing alcohol from liquid to a gas. (c) drying wood in a shed - is simply allowing Amy moisture present in the wood to evaporate. In all three of these cases the original material remains chemically unchanged. in (d) burning coal in a furnace - the cellular structure of the wood is broken down by heat - the individual wood cells are destroyed, turning it from cellulose to carbon.
