The Physical Chemist's Toolbox

Chemistry is the science of matter and the changes it undergoes. The science of matter is also addressed by physics, but while physics takes a more general, fundamental, and descriptive approach, chemistry is more specialized - concerned with the composition, behavior, structure, and properties of matter, as well as the changes it undergoes during chemical reactions. Chemistry is a physical science because of its study of various atoms, molecules, crystals and other aggregates of matter whether in isolation or combination, which incorporates the concepts of energy and entropy in relation to the spontaneity of chemical processes--
