Question

4 Identify Give an example of a physical change and an example of a chemical change.

Answer 1

A physical change involves a change in properties without a change in composition, while a chemical change involves the formation of new substances with different properties. An example of a physical change is melting ice, while an example of a chemical change is rusting iron.

Step-by-step explanation:

A physical change is a change to a sample of matter in which some properties of the material change, but the identity of the matter does not. An example of a physical change is when ice melts into water. The ice changes from a solid to a liquid, but its composition remains the same.

A chemical change, on the other hand, is a change in which a substance reacts with another substance to form a new substance with different properties. For example, when iron rusts, it reacts with oxygen in the air to form iron oxide, which has different properties than iron.

Answer 2

Answer below

Step-by-step explanation:

Physical changes dont change the chemical makeup of an object. An example would be to tear a piece of paper. Tearing the paper doesnt change how the paper was made chemically

Chemical changes on the other hand do change the chemical makeup of an object. An example of a chemical change would be to bake a cake. The reason being that the chemical makeup of the cake batter is changed so that the actual cake is formed.
