Lecture Notes, Statistical Mechanics (Theory F)

These lecture notes summarize the main content of the course Statistical Me-chanics (Theory F), taught at the Karlsruhe Institute of Technology during the summer semester 2012 and 2014. They are based on the graduate course Statistical Mechanics taught at Iowa State University between 2003 and 2005. 5

Lighter Than Air: Why Do Balloons Float?

We are so accustomed to swimming in air we forget that it is made of atoms and molecules (mostly nitrogen molecules, N 2), that have mass. This fact means that when the air molecules are displaced by an object, they push back with a buoyant force equal to the mass of the volume air pushed aside. Materials: • 12 small sheets thin tissue paper

Science Starts With a Question

Science is fun but can also be dangerous. Emphasize safety ... In a chemical process, the atoms that make up the original substances are regrouped into di!erent molecules, and these new substances have di!erent properties from those of the reactants. The total number of each

Porphyrins have a structure derived from porphine by replacing some of the hydrogen atoms around the outside with other groups of atoms. One

atoms while the O2 represents two oxygen atoms. Hydrogen peroxide molecules are very unstable and naturally decompose into water and oxygen gas. The chemical equation for this decomposition is: 2 H2O2 --> 2 H2O + O2. The equation above represents two hydrogen peroxide molecules decomposing into two water molecules and one oxygen molecule.

Therefore, a third model of the flow can be a microscopic approach wherein the fundamental laws of nature are applied directly to the atoms and molecules, using suitable statistical averaging to define the resulting fluid properties. This approach is in the purview of kinetic theory, which is a very
