One winter evening you fill a pint-sized plastic cup with ice and water to drink before going to bed. The cup is 1/4 ice and 3/4 water all at 0 Cc. Use the densities of ice and liquid water to find the mass of each. You set the cup on the kitchen counter, forget about it, and go to bed. The air in the kitchen is maintained at a constant 22 2"C by the central heating system of your apartment When you wake up in the morning, the cup contains liquid water at 22 2C. Part A What is the entropy change of the ice water during the process in which it went from 0C to liquid water at 22.2"C as you slept? Express your answer in jouies per kelvin. ASat = 285 J/K Subit Previous Answers v Correct Part B What is the entropy change of the air in the room due to the heat that flows from it into the contents of the cup?
