Rina is a physics student that enjoys hot tea. She wants to determine how much ice is needed to cool 0.200 kg of tea to an optimal drinking temperature of 57.8 C. The method Rina uses to prepare her tea results in an initial temperature of 82.0"C. The average mass of an ice cube from the ice tray she uses is 17.5 g and has a starting temperature of -9.10 C. Assume that the heat capacity of tea is the same as pure water, and that no heat is lost to the surroundings. What mass of ice mice in grams is needed to reach the optimal temperature of 57.8 C? How many whole ice cubes NV should Rina use to cool her tea as close as possible to 57.8-C? N= ice cubes
