2nd Lesson Practice

While studying for the unit test,  I found these links helpful, further explaining and offering practice on intermolecular and intramolecular forces and phase diagrams. I hope you find these helpful!

Lab

Yesterday in class, we performed the Specific Heat Capacity of a Metal Lab. In this experiment, we had to place hotter pieces of copper at a certain temperature into a cup of cooler water at a certain temperature to find the heat capacity of the copper. To find the heat capacity, we plugged in all the data from the lab into the equation -MCAT=MCAT. Here are some pictures from the lab:

First Lesson

      Once we finished our Biodiesel projects, we began our next unit: Energy and Phase Diagrams. On Friday, we learned about energy changes and how they are due to the rearrangement of chemical bonds. Most people believe that energy is stored in chemical bonds. However, the "addition of energy is always a requirement for the breaking of bonds, but the breaking if bonds in itself, does not release energy. " "Whether or not an overall reaction releases or requires energy depends upon the final balance between the breaking and forming of chemical bonds." That's where we came to endothermic and exothermic reactions. In an endothermic reaction, energy is gained from the surroundings of the reaction. In an exothermic reaction, energy is lost to the reactions surroundings. Here are diagrams that displays this concept:

In addition, we learned about calculating heat. To find heat or any of the other components in the equation, use the formula MCAT (M= mass, C= specific heat, AT=delta/temperature=change in temp)

Finished Biodiesel Video

Go check out our biodiesel video on YouTube!

In addition, for the next project, we are making a boat that will be fueled with the biodiesel we make in class. Here are a couple links to helpful websites that explain how a small boat should be made!
