5.2 Calorimetry | General Chemistry

Chad provides a comprehensive lesson on Calorimetry. He begins by defining a calorimeter and its heat capacity and then showing how it can be used to experimentally determine the enthalpy of a reaction. The specific heat of a substance is then defined and examples are worked showing how to calculate the quantity of heat absorbed or emitted from a substance based upon its change in temperature using the following equation:

q = mC(Delta T)

A standard heating curve is also presented, and it is demonstrated how to calculate the heat involved in a phase change as well. Multiple example calculations are performed at every stage of the lesson.

I've embedded this playlist as a course on my website with all the lessons organized by chapter in a collapsible menu and much of the content from the study guide included on the page. Check this lesson out at https://www.chadsprep.com/chads-gener...
