A 9.0*10^-2kg ice cube at 0.0 degrees celcius is dropped into a styrofoam cup holding .35 kg of water at 13 degrees celcius.
1) Find the final tempature of the system. Assume the cup and the sourroundings can be ignored. Answer in degrees celcius.
2) Find the amount of ice (if any) remaining. Answer in kg.
3) Find the initial tempature of the water that would be enough to just barely melt all of the ice. Answer in degrees celcius.
