9. To get your crush to like you back, you throw 200 pieces of 5-peso coins and 100 pieces of 10-peso coins into a wishing well. As you whisper your wish into the well, the wishing well talks back and tells you that your wish may only be granted if you calculate the entropy change of the throwing of the coins into the well until its temperature is in equilibrium with the water in the wishing well. The following data are given: 5-peso coin: Cp= 0.5 J/g-k, m =7.4 g each, initial coin temperature = 40C, 10-peso coin: Cp= 0.45 J/g-k, m =8.4 g each, initial coin temperature = 35C, g water: initial temperature = 10C, mass= 7 kg. Go make your wish come true
