When water freezes into ice, its volume increases. What happens to its mass?
It increases.No. When water freezes, it takes up more space, but the mass stays the same.
It stays the same.Yes. When water freezes, it expands to take up more space, but its mass stays the same. Mass is the measure of how much "stuff" is there. Freezing water does not create new water or add more "stuff". It just makes the water take up more space.
It decreases.No. The mass stays the same, even when the water freezes.
Water does not have mass.No. Everything that is made out of matter has mass.

SC.4.P.8.3 Explore the Law of Conservation of Mass by demonstrating that the mass of a whole object is always the same as the sum of the masses of its parts.
SC.5.P.8.1 Compare and contrast the basic properties of solids, liquids, and gases, such as mass, volume, color, texture, and temperature.

UT.5.I.1.b Compare the weight of a specified quantity of matter before and after it undergoes melting or freezing.
UT.7.I.2.a Use appropriate instruments to determine mass and volume of solids and liquids and record data.
5-PS1-2 Measure and graph quantities to provide evidence that regardless of the type of change that occurs when heating, cooling, or mixing substances, the total weight of matter is conserved.
