Question

Question 9 You take a 10-gram ice cube out of your freezer, which is at -10 C. You put the cube on the kitchen counter, get distracted, and forget about it. Later you come back to find the cube has melted into a puddle of water and come to room temperature, 15 C (it is a chilly day!). Specific heat of ice = 2220 J/kg. Heat of fusion of water = 333,000 J/kg. Specific heat of water = 4180 J/kg. What are: (a) The total heat energy transfered from the atmosphere to the ice/water? [4 points] (b) The change in entropy of the ice/water? [4 points] (c) The total change in entropy of the Universe? [2 points]
