Answer:
A physical change has occurred because the chemical make up has not been changed so the correct answer is A.
Answer: Option (A) is the correct answer.
Explanation:
A change that causes no difference in chemical composition of a substance is known as a physical change.
For example, breaking a pencil lead is a physical change because it divides the lead into two halves that is, no change in its chemical composition has occurred.
Whereas a change that brings difference in chemical composition of a substance is known as a chemical change.
For example, [tex]C + 2H_{2} \rightarrow CH_{4}[/tex]
Here, chemical composition of both carbon and hydrogen has changes as they chemically reacted together that leads to the formation of methane.
Thus, we can conclude that the statement a physical change has occurred, with no energy change, is true.
