Answer 1

b. The neighbor's pond freezes over in winter.

A change in the state of a substance would obviously be a physical change.

Answer 2

Answer: b. The neighbor's pond freezes over in winter.

Explanation: The physical states are the states whch are easily observed. Thus when transformation of one states of matter into the another, change is easily observed.
