Answer 2

Charcoal burning over grill is an example of CHEMICAL CHANGE.

But why?

• First of all, chemical change is defined as a change in which there is new chemical bond formation between the atoms of the substance. Also, the change will be reversible because new substances will be produced.

Here, charcoal is burning over grill. This is a COMBUSTION REACTION.

• The burning process will lead to formation of carbon dioxide, water and a lot of energy.

• Formation of these new products have been possible due to formation of new chemical bonds between the atoms.

$\star$ Hence, it is a chemical change.
