Question

select all the correct answers. what happens to water when it changes to ice? its density increases. its density decreases. its mass increases. its mass decreases. its volume increases. its volume decreases.

Explanation:

When water freezes to ice, mass is conserved according to the law of conservation of mass. But ice has an open - lattice structure which makes it less dense than liquid water, so density decreases. Since density $
ho=\frac{m}{V}$ and mass $m$ is constant while density $
ho$ decreases, volume $V$ must increase.

Answer:

Its density decreases., Its volume increases.
