In a physics experiment, a 0.100 kg aluminum calorimeter cup holding 0.200 kg of ice is removed from the freezer, where both ice and cup have been cooled to -5.00 degrees Celsius. Next, 0.0500 kg of steam at 100 degrees Celsius is added to the ice in the cup. What will be the equilibrium temperature of the system after the ice has melted? (c_aluminum=920 J/kgC, ice melts at 0 degrees Celsius
