1. The problem statement, all variables and given/known data A 70-kg log falls from a height of 25m into a lake. If the log, the lake, and the air are all at 300k, find the change in entropy of the Universe during this process. 2. Relevant equations delta S = Q/T 3. The attempt at a solution T= 300k M log=70 kg = 7000g Specific heat of wood = .420 j/gk h= 25 m I found the energy for the log Q= 882000j Entropy for it delta S = q/t = 29400j/k Then I don't know what else to do. Someone please help. I really NEED the HELP to solve this problem.
