Chemical Calorimetry

In this video step-a by-step description is given of a bomb calorimeter that is used to measure the internal energy of a sample.  If you burn as sample completely and measure the heat that evolves, you can find the thermodynamic internal energy.  Recall that internal energy is a state function and does not depend upon how the sample is burned.  Therefore if you burn a sample in a bomb calorimeter, say some cookies, the energy you measure is the same as released when you eat the cookie. Buy the General Chemistry Tutorial from MCH Multimedia:  General Chemistry can be used alone or in conjunction with any introductory chemistry text book. In this module, all the topics found in AP (Advanced Programs in High School), and college level General Chemistry courses are covered.  Learn in depth by working through the modules which are presented with clear verbal instructions and descriptions about chemical processes.  There are many places where you can plot results and do...
