Consider an ice cube with a mass of 1 g at 0.C that is left sitting on a kitchen table, where it undergoes gradual melting (the temperature in the kitchen is 25. C). (a) Calculate ASsys for the melting of the ice cube and the liquid water reaching thermal equilibrium with the kitchen. (b) Calculate the AS of the kitchen as it gives up heat to the melting ice cube/liquid water basically calculate ASsurr. (c) Calculate the net change in the entropy of the universe associated with this process. (d) is the result in part (c) reasonable? Explain Have each answer in J * K^-1
