Chem Blog Week 10

Before, I would confuse the three and said that they were the same thing. However, heat is the transferring of energy, while, the energy itself is just energy. Think of an Mp3 being energy and the iPod, computer, or CD being heat; it is just a different way the energy is stored but it is still the same energy.(More about that below!)

I also learned about how two substances of different temperatures  affect the overall temperature and the amount of heat when they are separately put into two containers of the same liquid at the same temperature. We did an experiment to find what would make a greater effect on the water overall: the hotter water with a smaller amount or the warm water with more water in that container. We found that the cup with more water in it, while being not as hot affected the temperature more that the other water. So the degree of hotness (temperature) depends on the speed of the particles and not the number of particles. The larger cup’s particle lacked in speed, but had greater mass. So mass and speed determined its greater energy input. While it took some people a while to understand what we had just learned, it came to me pretty easily (Once again,thanks Eureka!). It taught, along with Mr. Abud that the degree of hotness=temperature. The quantity of hotness=energy(heat).

We also learned that there are three principles of energy: Energy is a substance-like quantity that can be stored in a physical system, Energy can be “transferred” from one system to another and so cause changes in the system, and that energy still remains the same even after being transferred.
But, energy is not tangible. You can’t touch it or measure its mass on a balance. However, it can be transferred as well as stored. In Physics last year we were taught about different types of energy (kinetic, elastic, ect.) and that it would change. But like the example I was talking about earlier, just like music, even if energy moved in different ways, energy still remains the same. It doesn't change. Therefore, the quantity of energy can be changed, but the degree energy cannot be changed.On Friday Mr. Abud was not but we were able to communicate with him on someone’s iPad. He told us to work on a worksheet that dealed with boiling points and sumblimation. I am not very sure about that worksheet but hopefully we will talk more about it on Monday.

 Our thermoses are due on Monday and thankfully I didn’t leave to the last second because that would have been a nightmare! I am just putting on the finishing pieces. Hopefully it works well because I worked really hard on it. This week has been pretty stressful because I was gone on Friday and since the holiday is coming the week is even more busier than usual. But I’m getting through this weekend slowly but surely!
