You have been playing baseball in the middle of the summer and you have 0.25 kg of Gatorade in an insulated container sitting on the dugout bench that reached a temperature of 32 degrees C. You then add 3 ice cubes weighing 25 g at 0 degrees C to make it more enticing to drink. Assuming no heat exchanged to the surroundings what would be the final temperature of the gatorade? (Assume specific heat of gatorade is equal to waters)
