Answer:
A. It's the same as the original piece
Explanation:
The piece of matter is the same as that of the original piece.
When the mass of the two new pieces are combined, it the same as the single and whole one.
Mass is the amount of matter contained within a substance.
- When the whole is broken into two and there is no mass loss, the mass is retained when they are brought together again.
- In most cases mass is always conserved even physical changes.
