Question

Regan has an empty glass cup. It has a mass of 0.3 kg. She drops the cup on the ground and it shatters into several pieces. If she collected all of the pieces of the cup, how much mass would all of the pieces have combined?
A.
more than 0.3 kg
B.
exactly 0.3 kg
C.
There is no way to determine the mass of the shattered glass.
D.
less than 0.3 kg

Answer 1

The mass of the shattered pieces of the glass cup would be **B. exactly 0.3 kg**.

When the cup shatters, the total mass of the pieces is still equal to the mass of the original cup since mass is conserved in a closed system. So, no mass is gained or lost in the process of breaking.
