CHM 1032 Lecture Notes - Lecture 12: Crystal, Well-Order, Amorphous Solid
Document Summary
Scanning tunneling microscope image of a dna molecule. Dna is the hereditary material that encodes the operating instructions for most cells in living organisms. In this image, the dna molecule is yellow. The double-stranded structure of dna is discernible. The common states of matter are solid, liquid, and gas. Matter can be classified according to its states: solid, liquid, and gas. Water exists as ice (solid), water (liquid), and steam (gas). In ice, the water molecules are closely spaced and, although they vibrate about a fixed point, they do not generally move relative to one another. In liquid water, the water molecules are closely spaced but are free to move around and past each other. In steam, water molecules are separated by large distances and do not interact significantly with one another. In solid matter, atoms or molecules pack close to each other in fixed locations.
