when water freezes, what happens to the volume of the sample? it decreases. it increases. it stays the same.
Answer
Brief Explanations:
When water freezes, it expands. This is because the hydrogen - bonding in ice forms a more open, hexagonal lattice structure compared to the more closely - packed structure of liquid water. According to the formula (V=\frac{m}{\rho}) (where (V) is volume, (m) is mass, and (\rho) is density), since the density of ice ((\rho_{ice}\approx0.92\ g/cm^{3})) is less than the density of liquid water ((\rho_{water}\approx1\ g/cm^{3})) and the mass (m) remains constant during the phase change (assuming no loss or gain of water molecules), the volume (V) must increase.
Answer:
It increases.
