More Gas Laws
We learned a new equation which is going to be very helpful in chemistry. It is PV=nRT. P is pressure, V is volume, n is moles, R is a constant .0821, and T is temperature. We can use this equation to find grams of substance or any of these variables. It was a big help in the airbag lab we did as well.
Airbag Lab
I was a little nervous about this lab. We had to fill a ziploc bag with baking soda and vinegar to have it puff up, but not explode. We were simulating an airbag. My plan was to take all the measurements of pressure, volume, and temperature that day of the bag. Then I would use that to find the moles of baking soda and vinegar. Then I could use moles to find the grams or mL of product I needed in order to create the airbag. However, I was exempt from the lab because I had to take the AP Physic C test. I was very happy about that. No worries, here is some pictures, though.

First Quiz
We took our first quiz over the unit the other day. There was stuff on there I did not know so I got a C on the quiz. I don't remember learning about the kinetic theory, so I tried to use my prior physics knowledge to answer the questions. I also forgot was STP was. Now I know that it is 1 atm and 0 degrees Celsius. I guess I will have to study more for the test.

Gas Laws Intro
To start the unit, we learned about Charles, Boyles, and Avagadros gas laws. To make the summary a bit shorter, these all can be summed up to the combined gas law which is PV/nT. You can use these proportions to find different factors whether it's pressure, volume, moles, or temperature.

Energy test
We recently had a test over energy and phase changes. I did decent on the test with an 85%. I was hoping for a little higher, but I'm content with that. I had a pretty good understanding of the phase change graph and transfer of energy between phases. So here's some cool pictures relating to this unit.
