A maximum in refractive indices has been observed for the acetone + water system while the excess molar volume and the molar refraction change are all negative. Physical Change . I didn't want to waste the acetone to try and find out it doesn't work, because it's hard for me to get right now [no car] and I don't feel environmentally good about that. Physical reactions are reactions where the substance does not change into a new substance; for example, boiling is something seen in a physical change, which occurs in a physical reaction. No new substance is created during a physical change, although the matter takes a different form. Because physical changes do not change the identity of substances, they are often easy to undo. For example, boiling water is a physical change: it's still the same stuff. Question #85760. Chemically unaltered, the food shouldn't make you sick. change; chemical properties remain unchanged. Tweet. For instance, a physical change could be reversible and did not create a new substance. Expert Answer .
