             Chapter 1: Keys to the study of Chemistry
             · Chemistry: The study of matter and its properties, the changes that matter undergoes, and the energy associated with those changes.
             · Matter: Anything that has mass and volume, inertia, and energy(the ability to do work)
             · Properties: the characteristics that give each substance its unique identity. They can be 1.Physical (characteristic shown by themselves, without changing or interacting with another substance) A physical change leads to a different form of the same substance (same composition)
             · Intensive (independent of amount of material, ex. Density)
             · Extensive(depend on amount of material, ex volume)
             · 2.Chemical-how some material reacts in the presence of other. A chemical reaction occurs when a substance (or substances) is converted into a different substance. A chemical change leads to a different substance (different composition) (see attached 1.1)
             · The Three(four) States of Matter
             · Liquid conforms a container shape, but to the extent of the liquids own volume
             · Gas conforms container shape, but fills entire container.
             · Potential Energy- Energy due to position.
             · Kinetic Energy- Energy due to the motion of the object
             · Total Energy: Potential + Kinetic
             · Energy is an extensive property
             1.5 Measurement in Scientific study.
             · Temperature-kelvin-K ( how hot or cold a substance is relative to another substance)
             · Heat is energy that floats between objects that are at different temperatures.
             · Temperature is an intensive property.
             · T(in K) = T(in °C) + 273.15 (same size degree unit)
             · T(in °C) = T(in K) - 273.15
             · T(in °F) = 9/5(T) (in °C) + 32 (different degree unit)
             · T(in °C) = [ T (in °F) - 32] (5/9)
             · Amount of Subst...
