Ideal Gas Law

We learned about, yet, more laws. The next Law we learned about is The Ideal Gas Law.

This law can be  when converting one has to another. R, the universal gas constant, is equal to .0821 L atm/ mol.

Laws Laws Laws

This unit is focused properties of gases. So far we have gone over four of the seven gas laws. They are Boyle's, Charles', Avogadro's, and Combined Gas Law. They are all based off the master formula. These are all ideal gas laws



All of the laws keep at least on variable constant, and are either directly for indirectly proportional.

Phase Diagrams

A phase diagrams is a representation of the states of a substance in relation to temperature and pressure. This basically means that a phase diagram tells tells what physical phase (solid, liquid, gas), depending on the pressure and temperature. 

We also leaned about heat/cooling curves, which compares heat added and temperature

.

m=CΔt

After we were done with all of the biodiesle projects, we started on a unit focused on energy. During this unit we will be looking at numerous systems and determining how the energy flows in and out of the system.

There are two different types of systems, endothermic and exothermic. Endothermic reactions gain energy from the surroundings, with a net energy gain. Exothermic reactions loose energy to their surrounding , with a net energy loss.




Next we leaned about how to calculate heat using a formula that looks like M-Cat. m=CΔt allows you calculate change of heat, mass of sample, amount of heat, or temperature

. 

c is specific for a certain material, for example c for water is 4.186, while the specific heat capacity for copper is .385.

Put-Put Boat

Using the biodiesel from the lab we made Put-Put boats using it to race. Put-Put boats use steam engine to propel themselves forward, and can be made out of anything that floats. Not all we made were good, my group in particular.

Making Biodiesel

For the next part of the biodiesel unit, we made biodiesel from some pretty gross looking stuff. Taking used geese from chik-fillet a and some other compounds, then mixing them in heat, we were able to create burnable biodiesel. It wasn't particularity hard and can be done at home. (Warning: unpleasant smell)

Biodiesel

 Our next project in class is to put together a video to enter in a competition. The video must be supportive of biodiesel and the winner is the video with the most views. My lab partner decided to make a video of Uncle Sam encouraging the viewer to use biodiesel for the good of the U.S. We had to find a lot of facts on biodiesel, and we found this:
