Yes..there I go with the alliterations. again! I love them, I can't help it! I also love that the concepts of refrigeration and efficiency are becoming more and more real to us in physics class! I am linking to our notes from today's lecture. The diagrams are sketchy( literally) but hopefully they will help make it a bit more clear for you!
Here are the notes from today: Notes over refrigeration So why is it important to understand refrigeration? Why is it important to understand how closed engines work? What is the conservation of energy have to do with this? I love thermodynamics!
Also, for those of you who witnessed the vacuum demonstration (video link to follow on Monday), how did that help? Did you find it amazingly cool that as the pressure decreased the temperature actually did too! Remember from Chemistry last year "Pv-nrT"? The You tube song will forever be stuck in your mind! If you have forgotten it, allow me to remind you! pv-nrT Don't mind the swear words and the pimp/hoe reference! You touched the glass, you saw the temp.. you KNOW it became cooler! Now where is that heat going to go from in the fridge? Rembmer, heat will travel from a hotter to a cooler. Need that song too? Here it is Thermodynamics song- with puppets!
