1. Find why the solution of the Example: “Entropy increase on heat flow” (page 44-45) is not totally correct. In fact it is quite a rough approximation….
2. We pour a glass of water (m=0.2 kg) at temperature Ti=600 C in a lake with water at temperature T0=100C. Calculate the change in the entropy of the Universe due to this process. The specific heat of water is: cw=4180 J/(Kg.K)
3. Solve problem 5 on page 53.
4. Solve problem 6 on page 54
A famous British duo Flanders and Swan have a nice song about the laws of thermodynamic. You can download it (I suggest to listen it, it is funny) in mp3 format here, and you can get the verses here. Find the scientifically wrong statements in their song, and argue why it is wrong or not complete.
