Question

the difference between a physical change and a chemical change is that a chemical change makes a new substance. for example, when water freezes, it goes through a physical change, but it does not change into a different substance. choose the three items that describe physical changes.
a. rusting metal
b. boiling water
c. breaking ice
d. carving a wooden statue
e. baking a cake

Explanation:

• Physical changes don't form new substances. Boiling water (B) changes state (liquid to gas), breaking ice (C) changes state (solid to liquid), and carving a wooden statue (D) changes shape—all are physical. Rusting (A) and baking a cake (E) form new substances (chemical changes).
