As we will discuss in class, the change in the entropy of the surroundings is always given by the negative of the heat absorbed by the system divided by the temperature of the surroundings, i.e., Ssurr=Tsurrqsys. This is because the surroundings have infinite heat capacity so that any heat absorbed by the system has no effect on the temperature of the surroundings, and because the surroundings have infinite volume so that no change in the system's volume has any effect on the volume of the surroundings. For each of the changes of state described in problems 1,2 , and 3 above, calculate Ssurr and the corresponding change in the entropy of the universe, Suniverse=Ssys+Ssurr
