Problem
How much ice at –10 °C must be dropped into an aluminium cup containing 300 g of water at 20 °C in order for the temperature of the water to be reduced to 10 °C? The cup itself has a mass of 150 g and specific heat capacity 900 J kg−1 K−1 . Assume that no energy is lost to the surroundings.
