Question

Susan is investigating physical changes. To do this, she places some ice into a large bowl and seals it with a lid. She leaves the bowl on the counter for several hours until all of the ice has melted. Using a balance, Susan determines that the mass of both the water and the ice are equal. Why is the mass of the ice and the water the same? (SC.8.P.9.1)

Answer 1

Answer:

No mass loss

Explanation:

The mass of ice and the water in the different state are equal because the same of quantity of matter is present in both state of matter of matter.

• In essence, the mass of the physical change process is conserved.
• When mass is conserved, matter is neither created nor destroyed but can be changed from one form to the other.
• This is in compliance with the law of conservation of matter.
• So, no mass was lost in the physical change process and the mass will remain the same.
