Tina observed the following when she tested the specific gravity of milk to check for adulteration- the specific gravity was lesser than that of pure milk. She complained to the milk vendor and the next day checked the specific gravity again. This time it came in the range of the desired specific gravity. Can we be assured that this is pure unadulterated milk?
