Question

chemical and physical changes part a consider the images depicting change. which statement accurately describes a change taking place in one of the images? a the water in image ii is undergoing a chemical change because there is a change in phase. b the pipes are undergoing a physical change because theyre still pipes, nothing new is formed. c a chemical change is occurring in image ii because heat energy is being removed from liquid water. d the pipes in image i are going through a chemical change called rusting; the evidence is the color change.

Explanation:

A phase - change of water (image II) is a physical change, not a chemical change. Removing heat energy from liquid water to form ice is a physical change. The pipes in image I show rusting, which is a chemical change as a new substance (rust) is formed and color change is an indication of a chemical reaction. A physical change does not result in a new substance, and the statement about pipes in option B is incorrect as the pipes in image I are undergoing a chemical change (rusting).

Answer:

D. The pipes in image I are going through a chemical change called rusting; the evidence is the color change
