Ice cubes from the freezer weigh about 25 g and are at a temperature of -15.0 °C. Suppose I have a glass of ice tea (250 mL, 250.0 g), which is essentially all H₂O, at room temperature (22.0 °C) and I want to use ice cubes to cool it down to the temperature of a refrigerator (4.0 °C, 40 °F). How many ice cubes do I need to use? In order words, what mass of ice cubes are needed to get the combined system to 4.0 °C?
