What is conserved in physical changes?
A. shape
B. energy
C. mass ~~~
D. density
My answer is C. Am I right?
Nevermind I turned it in and I was right.
yes
Am I right or not? I need to get this done asap!
Yes, you are correct. In physical changes, such as melting, boiling, or dissolving, the mass of the system remains constant. Therefore, option C, mass, is conserved in physical changes.
But how can you figure this out on your own? One way to determine the answer is by understanding the concept of conservation laws in physics. The law of conservation of mass states that in a closed system (where no mass is entering or leaving), the total mass remains constant before and after a physical change. Therefore, whatever mass is present in the system at the beginning will still be present after the physical change occurs. This principle applies to various physical changes, such as changes in state or phase. By applying your knowledge of the conservation of mass, you can arrive at the correct answer, which is option C.
