Question

Match the given behaviors of water with their correct rationale. Use your observations about water and the reading you have done to draw conclusions about these behaviors. Drag the items on the left to the correct location on the right. Correct high specific heat Correct ice floats on water Correct cohesion Correct high heat of vaporization Hydrogen bonds between water molecules keep the molecules "sticking together." Heat energy first breaks hydrogen bonds before it increases movement of water molecules. As a result more heat is required to raise the temperature of 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. 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.

Answer 1

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.
