Question

Steve uses clay to model the law of

conservation of matter. First, he finds the
mass of a ball of clay on a balance. Then, he
molds the clay into a different shape without
adding or removing clay. Finally, he finds the
mass on a balance again.
How will Steve's results show the law of
conservation of matter?
A. The results will show that both the shape and
the mass have changed.
B. The results will show that the shape has
changed, but the mass is the same.
C. The results will show that changing the shape
has changed the mass of the clay.
D. The results will show that the larger the shape,
the greater the mass.

Answer 1

The law of conservation of matter states that for any system closed to all transfers of matter in energy, the mass of the system must remain constant over time.

In other words, it doesn’t really matter what shape the thing is, it will always have the same mass unless you take some of the shape away or add more of it

The correct answer would be B, the shape changed but the mass is the same

I hope this helps!! <3
