You have 240 g of piping hot water (or coffee) at 95 degrees C in your cup. You put a 15-g ice cube in the water and let it reach equilibrium. Then, add a second cube and so on. The ice cubes are taken out of a freezer kept at -20 degrees C. 

Find the temperature of the water in degrees C after the first ice cube is added. Explain your reasoning clearly and completely. Treat the cup as a perfect calorimeter. 2. Apply the same method to calculate the temperature of the water after 2,3,4,5 ice cubes are added. Complete the table below. You don't need explain the steps.
