Properties of Water
Water exhibits unique properties that make it essential for life processes. These properties arise from its molecular structure and hydrogen bonding capabilities.
Definition: Cohesion is the attraction between water molecules due to hydrogen bonding, while adhesion refers to water's ability to attract different substances.
Example: Surface tension, resulting from cohesion, enables insects to walk on water and allows rocks to skip across ponds.
Highlight: Water's unique density properties cause ice to float, as it becomes less dense when frozen, unlike most other substances.
Vocabulary: Vaporization refers to the energy required to convert liquid water to gas, contributing to water's temperature stability.
