Blog Week 11

This week in Chemistry we made thermos. I worked alone on this project, I made the thermos; then I made the google presentation. My thermos worked very well, I had 98.2% energy retention and only a six Kelvin drop. To make my thermos I used a monster trail mix container with polyfill in it. Inside the polyfill insulation was a pencil holder container and wrapped around that container was foil and it was also filled with foil. Then on the monster container's top was foil on both sides. The energy transferred from the water to the foil and insulation which was the polyfill, by a process of translation called heat. Heat is not the energy nor is it stored it just transfers energy from one system to another. I think my thermos worked very well. If I were to improve it I would have got a better top, one that wasn't plastic. Maybe one that was metal or styrofoam. I also, feel that I did very well on my presentation, I explained everything. I even did my measurements for the monster mix container, to prove it wasn't to big. I also added pictures and explained them. I feel I did very well on this project and that wouldn't be much I'd change.
