I cannot believe the trimester is almost over. Junior year flies by. I really don't remember what I've been doing that past three months. My grades are still horrible right now, but next trimester will probably be better since I don't have football. This week of chemistry, we basically just reviewed everything and learned about the different characteristic of phases of matter. It's pretty easy. I just need to review and be ready for the test next week. Next week is going to be stressful because I'll have basically tests in all of my classes, and they determine my grade for the trimester.
Here is my basic knowledge that I learned from the week. Liquid is basically when the molecules spread out but yet still attracted with one another, allowing liquid to freely flow around and take in any shape. Solid is when molecules are tightly compacted in a volume, the electrons are vibrating like a "sea" which is why it's very electric and heat conductive. Whereas gas, the molecules are way far apart from each other, going everywhere. We also learned about vapor pressure in the past week. The greater the intermolecular bonds the greater the viscosity. As viscosity increases, the boiling point increases because the intermolecular bonds are greater. Lattice energy is all based off form Couloumb's law, so really self explanatory to see the lattice energy of a molecule. Ionic solids is the strongest and trump all of the other kind of solids. Vapor pressure is basically how easily the molecules in liquid can break apart due to the attraction force within the molecule. Vapor pressure and boiling point are inversely related. On the test, I need to focused on how I word my explanation which is really important to show that I know the concept thoroughly. I am a little bit stressed out right now for the finals as well, along with all of my tests coming up. I need to find a stress relief for myself in order for me success in life I guess.
Overall, these are my general summary of what I learned this week from chemistry. I was sick on Friday, so I didn't really know what we learned on that day. I still have lots of studying to do for all of my other classes. Especially math, I really need to do well on the next test otherwise I'll be in trouble. Although I didn't begin my junior year with a strong start, I am very determined to get good grades for the rest of the years. Lastly, I can't wait for robotics season to start. It's time to put my hands on the machines once again and make cool things. I hope that we will make nationals again this year, where we can skip a week of school and just have fun.
