Val cut a cold apple into slices, placed the slices on a plate, and left the plate on the kitchen counter. Over the next two hours, Val observed that the apple slices started to dry out and turn brown. She also noted that the apple slices warmed to room temperature, and a couple of fruit flies started to fly around them. Which of the following would be a good Claim and Evidence explaining if a chemical or physical change occurred?
A. This is an example of a chemical change. My evidence that supports this claim is that the apple is room temperature.
B. This is an example of a chemical change. My evidence that supports this claim is that the apple changed color.
C. This is an example of a physical change. My evidence that supports this claim is that the apple changed color.
D. This is an example of a physical change. My evidence that supports this claim is that the apple is room temperature.
