An ice chest at a beach party contains 12 cans of soda at 2.90 °C. Each can of soda has a mass of 0.35 kg and a specific heat capacity of 3800 J/(kg C°). Someone adds a 9.12-kg watermelon at 27.5 °C to the chest. The specific heat capacity of watermelon is nearly the same as that of water. Ignore the specific heat capacity of the chest and determine the final temperatureTof the soda and watermelon in degrees Celsius.
