Hi! My name is Joshua Davis and I am a high school sophomore form Brunswick, Georgia. For my chemistry class, I have to do a science experiment. My experiment involves relating a gas's temperature to its pressure using Boyle's Law and Charles's Law. My science project is a combination of two projects from the following sites: http://www.sciencebuddies.org/science-fair-projects/project_ideas/Chem_p018.shtml?from=Home http://www.sciencebuddies.org/mentoring/project_ideas/Chem_p011.shtml At the bottom of these two pages, it offers the oppurtunity of a more advanced project using statistical mechanics. I think I know which statistical mechanic ensemble to use: either isothermal-isobaric ensemble or the canoncial ensemble. I found my information on these pages: http://en.wikipedia.org/wiki/Ideal_gas_law#Derivation_from_the_statistical_mechanics http://en.wikipedia.org/wiki/Isothermal–isobaric_ensemble Can somebody tell me which one to use and how to use it because this stuff looks pretty complicated. Please don't ignore me !!!
