For this experiment, the point was to look at the properties of a wonderful substance called dry ice. What we did with it was, we put it on our table and then we messed around with it however we felt like. Something that my group decided to try was using a balloon that Andrew gave us and we put a large chunk of dry ice in the balloon and then we poured out some water into the balloon and tried to close the balloon off so that we could get the most expansion in the balloon itself. We got a big balloon when we were done but we had hoped that we could get a pop out of the balloon but we decided that it was expanding too slowly for it to puncture the balloon at a high rate so that was disappointing. The main point of the experiment was to measure the expansion rate of dry ice when it changed from a solid to a gas, and that's why we decided to put it in the balloon. Although that was an inaccurate measure of conversion it still portrayed to us that the exchange from solid to gas is a lot because the molecules are separating more and making a large space in between them. The idea of our experiment worked pretty well because it's pretty easy to do and there's not much to go wrong and we did as we were instructed for the most part. The balloon inflated a lot and looked cool. The sizzling of the dry ice was also intriguing to listen to.
It seems that on a molecular level that the particles of the dry ice, when changing from a solid to a gas are probably expanding a lot and making the space between the pieces of it much larger. We were wondering what was happening between the molecules to make them want to separate at just room temperature. The fact that it has such a low exchange rate that it melts at room temperature and converts into a gas. We didn't have the resources to look into the facets of this but we didn't have the time or the will to look further into it.
We got pretty decent results on this project because we were just asked to see if we could roughly quantify the change rate for dry ice trying to see how much gas was produced when it sublimated and we did that, but the whole popping part not happening sucked. It was a pretty simple endeavour and that's why I think we got good results and also our knowledge in such things as chemistry and science probably contributed to that at least a little bit. I think I performed pretty well in this activity even though my group mates wanted to do a lot of the work I still got to contribute a bit and I'm glad that that's the case.
I worked yet again with Avery and the gang, because we always work well and this was no exception so that went well as always. We did our work just like everybody else and there wasn't much difference between us and them because this lab was so structured and hard to mess up. It was kind of fun but doing it so slowly and all along with everybody else in the class did dull it down a bit. I contributed my usual bit which was helping out in what ways I could while still mostly equally splitting the work load evenly so no one feels under or overwhelmed. We made sure that everybody stayed pretty whelmed.
If I could do this project again I would definitely make sure to more accurately measure the amount of gas produced form the block of dry ice than a balloon because it would be interesting to see how much there actually was and just be more scientific about it. If I was going to organize another group to work with for another experiment in this class, I would definitely consider my three close working partners while also considering asking other people with often less singular and more like minded ideas later on. I didn't see any real way to continue this experiment seeing as it was so closed ended and I wouldn't have really tried to explore one either seeing as I didn't have much of an attraction to it in the first place. I didn't get any new information from this project because it was all pretty standard simple science.
