An ice chest contains 12 cans of soda at 50o C. Each can of soda has a mass of 0.35 kilogram and a specific heat capacity of 3800 J/(kg Co). Someone adds a 6.5 kilogram watermelon at 27oC to the chest. The specific heat of the watermelon is nearly the same as that of water. Neglect the specific heat capacity of the chest and find the final temperature of the watermelon and soda.
