Read through the following article on Entropy. (I know, it is sort of long!) Did this article clarify material for you? If so, what and how?

Also attached is a couple of youtube video that are interesting.
I think this article explained entropy and its uses well. I found it useful in better understanding some of the questions on the worksheet. Although I don't think I learned anything new from the article. I did like the examples of Nigra Falls and the car. I now understand better what exactly spontaneous means within the perspective of chemistry.
ReplyDeletePrior to reading the article, I knew the general definition of entropy and the second law of thermodynamics. However, the article did help clarify the concept by giving a few real world examples. Learning about the molecules of water on top of Niagara Falls, molecules in air limited to car tire's volume, and atoms vibrating in a hot metal plan helped me better understand examples relating to entropy surrounding us.
ReplyDeleteIn the article, the author's addition of real life examples of entropy helped to clarify its definition. The examples of the hot pan cooling and the chemical reactions explained as the types of reactions that use the "how much" category, where energy is transferred, was very helpful. Along with the "how much" example, the cream and coffee, and perfume in air examples helped explain how entropy can be viewed as "how widely" atoms/molecules are dispersed, rather than just the quantity.
ReplyDeleteI found the examples most helpful in this article. Especially the photosynthesis example because it explained the diversion dispersing energy and the isolated system well. The plant can be considered an isolated system but that moght lead to incorrect conclusion about the entropy because the plant it also part of a larger system.

ReplyDeleteI found that this article helped me clarify the idea of entropy related to the system and the surroundings. The concept of how the molecules disperse helped me create a mental picture to better understand the energy involved in entropy. The examples within the article were extremely useful to better understand the terms of entropy and energy related to the speed of molecules.
ReplyDeleteI think that it's interesting to learn about the same concepts but from different science fields, ie chemistry, physics, etc., and coming back around in full circle with this total knowledge. This article helped clarify and reiterate what can be considered surroundings and different types of systems. It did this through providing examples in real life entropy examples and makes it easier to visualize what is going on.
