A cooler contains 12 cans of soda at 5oC. Each soda has mass 0.35 kilogram and a specific heat capacity of 3800J/kgC. A 6.5 kilogram watermelon at 27oC is added to the cooler. The specific heat capacity 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.
