True or false water is more dense when it is solid

False, it is less dense as a solid because the hydrogen bonds that make up the crystallized structure cause the molecules to push farther apart which is also the reason why ice floats and lowers the density.

Sugar and water are chemically combined.(a solution is chemically combined while a mixture is mixed together without bonding the molecules)

Non metal is an element or substance that is not a metal metal is a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivitymetalloid is an element (e.g., germanium or silicon) whose properties are intermediate between those of metals and solid nonmetals. they are electrical semiconductors.
