Flashcards
Surface Tension of Water
Surface Tension of Water
High surface tension results from hydrogen bonding between water molecules.
Polarity of Water
Polarity of Water
Water's polarity allows it to adhere to other polar molecules.
Cohesive Nature of Water
Cohesive Nature of Water
Cohesion causes water molecules to stick to each other, enabling insects to glide.
