If there is 8 g of a substance before a physical change, how much will there be afterwards? A. 0 g
B. 4 g
C. 8 g
D. 16 g

Hii :))

Well, I think that the mass of the substance before & after a physical change will remain the same because according to the law of conservation of mass, mass can neither be created nor destroyed in a chemical/physical reaction So, the mass of the substance will remain as even after the physical change.
