An ice chest at a beach party contains 11cans of soda at 6°C. Each can of soda has a mass of 0.34 kg and a specific heat capacity of 3900 J/(kg·°C).Someone adds a 6.3 kg watermelon at25°C to the chest. The specific heat capacity of watermelon is nearly the similar as that of water. Ignore the specific heat capacity of the chest and decide the final temperature T of the watermelon and soda.
