I need some help with this problem. Here is the problem. Btw, this is problem #5.4 from Equilibrium Thermodynamics 3rd edition by C.J. Adkins
1*10^-3 m^3 of water is warmed from 20 to 100 degrees Celsius A) by placing it in contact with a large reservoir at 100 degrees Celsius, B) by placing it first in contact with a large reservoir at 50 degrees Celsius until it reaches that temperature, and then in contact with the reservoir at 100 degrees Celsius, and C) by operating a reversible heat engine between it and the reservoir at 100 degrees Celsius. In each case, what are the entropy changes of 1) the water 2) the reservoirs, and 3) the universe?
