Based on the given pictures, the claim of whether the change is a chemical change or a physical change cannot be determined by just looking at the pictures. More information or evidence is needed to make a definitive determination.
To determine whether the given scenario is a chemical change or a physical change, you can consider the definition and characteristics of each type of change.
A chemical change, also known as a chemical reaction, involves the formation or breakage of chemical bonds. It results in the formation of new substances with different chemical properties. Common examples of chemical changes include burning, rusting, and fermentation.
A physical change, on the other hand, does not involve the formation of new substances or the breaking of chemical bonds. Instead, it only alters the physical state or appearance of a substance, such as changes in shape, size, or phase (solid, liquid, gas). Some examples of physical changes include melting, freezing, and dissolving.
In the given scenario, a forest fire is depicted in a series of pictures, showing the fire in progress and then extinguished. Based on this information, we can conclude that the change observed is a chemical change. This is because during a fire, the combustion of organic material occurs, resulting in the release of heat and the formation of new substances, such as ash, smoke, and gases.
Therefore, the correct response is:
Chemical change
