(b) What is the entropy change of the ice (including the melting of the ice and possible warming of the water from the melted ice)? (c) What is the entropy change of the water as it cools down? (d) What is the total entropy change of the ice-water system? (e) Include a labeled graph of temperature versus heat added for this situation.

An athlete whose mass is 70.0 kg drinks 16.0 ounces (454 g) of refrigerated water. The water is at a temperature of 35.0F.
