1. A student wants to cool 0.25kg of diet soda (mostly water), initially at 25°C, by adding ice initially at -20 °C. How much ice should she add so that the final temperature will be 0 °C with all the ice melted if the heat capacity of the container maybe neglected? Cwater = 4, 186 J/kg-Cº Answer: Cice=2.09 x 103³ J/kg-Cº L₁= 3.35 x105 J/kg mice = 0.069 kg (69 g)
