Question

A 9.0×10^(-2)-kg ice cube at 0.0 °C is dropped into a Styrofoam cup holding 0.35 kg of water at 12 °C. Part A: Find the final temperature of the system. Assume the cup and the surroundings can be ignored. Part B: Find the amount of ice (if any) remaining. Part C: Find the initial temperature of the water that would be enough to just barely melt all of the ice.

Step 1

The heat of fusion for water is 334 J/g, and the mass of the ice cube is 90 g (0.09 kg * 1000 g/kg). So, the heat required to melt the ice cube is Q = m * Lf = 90 g * 334 J/g = 30060 J. Show more…
