The Science of Life Lecture Series

Hello internet, and welcome to the Science of Life General Chemistry lecture series.  In this session, I'll cover some of the properties of the materials in which chemists are interested. Properties There are two types of properties which we deal with in General Chemistry.  There are more types, but there are specifically two that are important for this course.  There are physical properties (properties which do not describe the chemistry of the substance, such as the phase) and chemical properties (which do describe the chemistry of the substance, such as whether or not it's an acid).  Properties can also be classed as either extrinsic (depends on the quantity of the substance, such as the mass) or intrinsic (does not depend on the quantity, such as melting point).  Boiling point is an intrinsic physical property; it doesn't describe the chemistry of the substance (alas the physical part) and the boiling point at that pressure doesn't change with quantity of sub
