Question

which term describes a change that occurs with no new substances being formed?
a. physical change
b. bond change
c. energy change
d. chemical change

Explanation:

In a physical change, the substance's form or appearance changes, but its chemical composition remains the same, meaning no new substances are formed. In contrast, a chemical change results in the formation of new substances, a bond - change is related to chemical reactions where bonds are broken or formed (resulting in new substances), and an energy change can accompany both physical and chemical changes but doesn't define a change without new - substance formation.

Answer:

A. Physical change
