  I.  THERMOCHEMISTRY

Here is a very good introduction to the two types of calorimeters that allow us to calculate the value of ΔH or ΔE of a chemical reaction:

(1)  coffee cup calorimeters (that operate at a constant pressure and allow us to calculate the value of ΔH (change in enthalpy) of a chemical reaction, and

(2)  bomb calorimeters (that operate at a constant volume and allow us to calculate the value of ΔE of that chemical reaction).

Fritz Haber
 
Hank introduces us to the brilliant and heartless Fritz Haber, a great mind who is considered "the father of chemical warfare," but who also made discoveries and innovations that helped lead to the Green Revolution which is credited with preventing the starvation of over a billion people.
