Which one of the following is a physical change?

b. Grape juice left in an open unrefrigerated container turns sour.
c. When ignited with a match in open air, paper burns

e. When treated with bleach, some dyed fabrics change color.

Answer 1

I believe it is A because a physical change is something that can be changed back to where a chemical change can not be such as burning something.
