Explain: 1. Ice has lower density than Water.
Answers
Answer:
Hey !!
Explanation:
Ice actually has a very different structure than liquid water, in that the molecules align themselves in a regular lattice rather than more randomly as in the liquid form. It happens that the lattice arrangement allows water molecules to be more spread out than in a liquid, and, thus, ice is less dense than water.

Answer:
Ice has a lower density than water because of hydrogen bonding and cage-like structure of ice.
Ice has hexagonal three-dimensional crystal structure (as per X-ray crystallographic data). This hexagonal crystal structure is formed due to intermolecular hydrogen bonding.
When ice melts, some of hydrogen bonds break and some empty spaces are occupied by water molecules. Liquid water molecules are more closely packed than molecules in ice. Hence, ice has lower density than water.
