Question

A plant grows 3 inches in one month. why is this a physical change?

A.The size of plant has changed
B.The plant makes energy from the sun to grow the flower.
C.Heat of combustion from the sun helps grow the flower.
D.Special structures in the plant react with sunlight to make the flower.

Answer 1

Hey there!

I believe the answer is A because it's physical and you can "see" it grows(if you're next to it the whole month) and the others you can't really see. Like you can't see energy from the sun or heat or the special structures of the plants that react with sunlight to make the flower.

Hope this helps!
