Choose one property of water that makes it unique. Describe the property and explain the chemical or physical basis behind it.
Answer (2)
Water has a density of 1. This is unique because it sets a guideline to classifying other substances, whether or not they float in water (Whether or not their density is above or below 1). This is a physical property as it measures other physical properties.
Water's solid phase, ice, is less dense than its liquid phase, which allows ice to float. This phenomenon is due to the formation of hydrogen bonds that create an open crystalline structure in ice. This unique property has important implications for life in aquatic environments.
