I can hardly remember anything from last week because of all the stuff over the weekend. That's probably the reason why I forgot to get this post up on the web.
Oh right, we are on states of matter.
It doesn't seem like much news to me that there are these three states of matter that have respective levels of energy. I recall learning about this stuff in 4th grade, so for the time being it's been review. Now we're going into some more complex stuff like adding energy into the system and experiencing expansion. That seems a little new so I've been a little more interested in the new stuff.
I actually don't recall observing liquid expansion (except for thermometers) with the addition of energy. So at first I was a little startled to see this. How is that possible? I kept asking myself that until I learned that this expansion occurs at all states of matter, and I realized that we touched the topic of expansion/contraction in elementary school. It's simple. Energy brought into the system expands the material, and I would speculate energy exiting the system causes the contraction process to the initial state. That's pretty cool, this whole idea once you realize that all of this occurs at the molecular level. It can be difficult to think that the countless amount of particles within a material all pitch-in to the process. Pretty intriguing to me.
Concerning assessments, I'm at a stalemate whether or not to re-assess. I normally do, but I keep forgetting and I'm wondering if it will even help. Other than that there are no new updates on that topic with the exception that I am having some trouble with active-grade.
