Question

Ice floats on water. For most other substances, however, the solid sinks in the liquid.

Classify each of these statements as true for water, or true for most other substances.

A) High pressure will cause the solid to become liquid.
B) In a phase diagram, the solid-liquid coexistence line has a negative slope.
C) The solid is more dense than the liquid.
D) The molecules are closest in the solid phase.
E) High pressure will cause the liquid to become solid
F) The solid is less dense than the liquid
G) The molecules are closest in the liquid phase
H) In a phase diagram, the solid-liquid coexistence line has a positive slope

Answer 1

Answer:The solid is less dense than the liquid

Step-by-step explanation:

Ice is less dense than water because of the crevices or spaces in the lattice structure of ice. Liquid water has a much greater density than solid water because its molecules are more compactly packed than in ice. Ice has large spaces between the hydrogen bonded water molecules hence less density than the liquid. Being less dense than !liquid water, it floats on water.
