An ice chest at a beach party contains 12 cans of soda at 4.05 °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 6.21-kg watermelon at 24.0 °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 temperature t of the soda and watermelon in degrees celsius.
