Blogger, you have failed me! I posted a blog but you didnt. Anyways, I hope everyones first weeks of the new year have been awesome!!! So this weeks we're learning about thermodynamics and heat!! Fun, fun fun! :) The first law of thermodynamics is heat equals work done plus internal energy (Q=W+U). There are many types of processes: isochoric, isothermal, and isobaric. That is when volume doesn't change, temperature doesn't change, and pressure doesn't change respectively. So you may be wondering whats up with the picture of the refrigerator above?? Well, in most cases, such as with heat engines, the amount of heat going in is greater than the heat going out. But since a refrigerator is generating cold air and maintaining a cool temperature, there is a negative net work because there is more heat going out than in. Weird, your refrigerator is doing negative work!
