Today we spent a lot of time going over Assignment H3 on combined heat problems. This was in preparation for the take home assignment on calculating quantities of heat. I handed this out in class today. We began to learn about enthalpy today. We learned how they measure the energy that is available in foods. One can simply use that food to heat up water and determine the heat change in water or one can break done the food into its parts (fat, carbs, protein, etc) and know the energy in the parts, one can figure out the energy of the whole. This will apply when we are finding the energy present in chemical reactions.
This was all covered in the powerpoint called Enthalpy. We covered slides 1-11. Students were given a notes handout that they used to follow along with the presentation. This allowed students to just listen the presentation. Tomorrow we will finish the notes on Enthalpy.
