Question

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 they are 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 is a physical change, not a chemical change, so A is incorrect. Pipes remaining pipes with no new substance formed is a physical change, but we need to check all options. Removing heat energy from liquid water causing a phase - change is a physical change, not a chemical change, so C is incorrect. Rusting of pipes is a chemical change as it involves the formation of a new substance (rust) and is indicated by a color change.

Answer:

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