Water and bonding
High energy needed to change temperature. Less dense when solid High energy needed to change temperature. Less dense when solid. Good solvent. High surface tension. What are unique properties of water?
The attraction between like molecules. What is cohesion?
Regarding water molecules: Oxygen atom is slightly negative, hydrogen atoms are slightly positive. What is polarity?
The attraction between molecules of different substances. What is adhesion?
Covalent bonding that makes surface tension in water possible? What are hydrogen bonds?
