Verified step by step guidance

Understand the concept of density: Ice is less dense than liquid water because the molecular structure of ice forms a lattice that takes up more space, making it less dense.

Review specific heat: Specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius. Water has a high specific heat compared to many other substances, meaning it can absorb a lot of heat without a significant change in temperature.

Examine heat of vaporization: The heat of vaporization is the amount of energy required to convert a liquid into a gas at its boiling point. Water has a high heat of vaporization, which means it requires a lot of energy to change from liquid to gas, more so than many other substances.

Consider polarity: Water is a polar molecule due to its bent shape and the difference in electronegativity between hydrogen and oxygen, leading to a partial positive charge on hydrogen and a partial negative charge on oxygen.

Based on these concepts, identify the correct statement: Liquid water has a higher heat of vaporization than most other molecules, which is a key property that affects its role in climate and biological systems.
