Question

ice floats on water because it becomes _ dense when it freezes
o less
o more

Explanation:

When water freezes to form ice, its volume increases while the mass remains the same. Using the density formula $
ho=\frac{m}{V}$ (where $
ho$ is density, $m$ is mass, and $V$ is volume), an increase in volume $V$ with constant mass $m$ leads to a decrease in density. Objects float when their density is less than the density of the fluid they are in. Since ice has a lower density than liquid water, it floats.

Answer:

less
