Question

the density of water at 0°C is more than that of ice at at the same temperature. why?​

Answer 1

Explanation:

When water freezes at 0°C, a rigid open lattice (like a web) of hydrogen-bonded molecules is formed. It is this open structure that makes ice less dense than liquid water.

Answer 2

Answer:

In liquid water, molecules are attracted to each other and temporarily held together by hydrogen bonds. When water freezes at 0°C, a rigid open lattice (like a web) of hydrogen-bonded molecules is formed. It is this open structure that makes ice less dense than liquid water.
