Question

according to conservation of mass, what is the mass of ice made from a certain mass of water?
a greater than the water
b changes according to temperature
c equal to that of the water
d less than the water

Explanation:

The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction or physical change. When water freezes to form ice, it is a physical change. The number of water molecules remains the same, just their arrangement changes. So, the mass of ice should be equal to the mass of the water from which it is formed.

Answer:

C. equal to that of the water
