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 almost the same as that of water. Ignore the specific heat capacity of the chest and decide the final temperature T of the soda and watermelon.
