CHEM 1150 Chapter Notes - Chapter 1: Trailing Zero, Boiling Point, International System Of Units
Document Summary
Chemistry: science that seeks to understand the behavior of matter by studying the behavior of atoms and molecules. Matter: substance that takes up space and has mass. Physical changes do not alter the order of atoms in a molecule. Physical properties: smell, taste, appearance, melting point, boiling point, density. Chemical changes alter how atoms are connected in a molecule. Law of conservation of energy states energy can neither be created nor destroyed. Precision: how close successive measurements are. (ie. 6. 23, 6. 20, 6. 17) Accuracy: how close measurements are to what they should be. *remember the acronym* the great man king henry died by drinking chocolate milk monday night puking. The b in by stands for the base unit you are starting with (for conversion factors). You must also know that the powers start with 12 and decrease by three each time until you reach kilo, then they only decrease by one.
