Match the given behaviors of water with their correct rationale. Use your observations about water and the reading you have done
kap26 [50]

Answer:

Heat energy first breaks hydrogen bonds before it increases movement of water molecules - High specific heat

As water freezes, the hydrogen bonds form a crystalline lattice which keeps the molecules at a consistent distance leading to a density lesser than liquid water- Ice floats on water

A large amount of energy is needed to convert liquid water, where the molecules are tied by hydrogen bonds, to water vapor, where they are not - High heat of vaporization

Hydrogen bonds between water molecules keep the molecules "sticking together." - Cohesion

Explanation:

Water is a molecule composed of two atoms of hydrogen and one atom of oxygen. Water is a very unique substance with properties that are unexpected of a molecule its size. Some of the unique properties of water include:

Its high polar nature, High-specific heat, High heat of vaporization, the lower density of ice. One of the reason for these unique properties is strong cohesive forces between water molecules.

Cohesion: Hydrogen bonds between water molecules keep the molecules "sticking together."

Polarity: Water molecules are polar, with partial positive charges on the hydrogens, a partial negative charge on the oxygen because oxygen is more electronegative than hydrogen. As a result, water is a good polar solvent.

High specific heat: Heat energy first breaks hydrogen bonds before it increases movement of water molecules.

Lower density of ice: As water freezes, the hydrogen bonds form a crystalline lattice which keeps the molecules at a consistent distance leading to a density lesser than liquid water, therefore, ice floats on water

High heat of vaporization: A large amount of energy is needed to convert liquid water, where the molecules are tied by hydrogen bonds, to water vapor, where they are not.
