Document Summary

Water is a polar molecule having a positive and negative side: a molecule is a group of atoms held together by chemical bonds. Chemical bonds:the energy relationships between atoms that hold them together; are formed when electrons are shared between atoms or moved from one atom to another: water molecules held together by hydrogen bonds. Hydrogen bonds form when the positive end of one water molecule bonds to the negative end of another water molecule o. Cohesion: the ability of water molecules to stick to each other, creating surface tension. Adhesion: the tendency of water molecules to stick to other substance. Thermal characteristics of water: heat: energy produced by the random vibrations of atoms or molecules, temperature: an object"s response to input or removal of heat; water temperature affects its density (solid, liquid, gas) Solid (ice): has a lattice structure that is hexagonal at the molecular level.
