The temperature at which electrical resistance is zero is called the critical temperature (Tc) and varies with the individual material. For practical purposes‚ critical temperatures are achieved by cooling materials with either liquid helium or liquid nitrogen. The following table shows the critical temperatures of various superconductors:

Bette Nesmith Graham As electric typewriters came into widespread use after World War II‚ Bette Nesmith Graham and countless other secretaries let out a collective groan. The new machines did make typing easier‚ but their carbon-film ribbons made it impossible to correct mistakes neatly with a pencil eraser. As a result of this predicament‚ Graham ended up inventing one of the most widely used office products of the 20th century. Born in 1924 in Dallas‚ Texas‚ Bette Graham dropped out of high

Lab 5: Preparation of Synthetic Banana Oil September 20th‚ 2012 Purpose: The main purpose of this experiment was to synthesize banana oil (isopentyl acetate.) Ester are often prepared by the Fischer esterification method‚ which involves heating a carboxylic acid with an alcohol in the presence of an acid catalyst. Theory: Synthesize isopentyl acetate by combining isopentyl alcohol with acetic acid and sulfuric acid and then heating the reaction mixture under reflux for an hour. The alcohol
