CHEM 101 Lecture Notes - Lecture 4: Condensed Matter Physics, Kilogram
Document Summary
~ study of matter- what stuff is made of. ~ matter: anything that has mass and takes up space. ~ study of the characteristics of matter how can characteristics be explained. ~ study of changes of matter what happens to matter in a chemical reaction. ~ using what you know to solve new problems. ~ ancient philosophers came up with their ideas of what matter was made of: Democritus: eventually, you will get to a small enough level, you can"t divide it any more (called these smallest divisions a-tom=no cut) Aristotle: all matter is made up of four elements; Also, it is impossible to see these smallest divisions of matter, so they have to be imagined, since water, air, earth, and fire. Science today experimentalists. they can"t be seen homogeneous: you can vary the components compound: the components can"t vary. Matter is typically classified into 3 states, based on the arrangements of the particles that make up the substance.
