Question

An ice chest at a beach party contains 12 cans of soda at 3.47 ?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 9.47-kg watermelon at 28.2 ?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.

An ice chest at a beach party contains 12 cans of soda at 3.47 ?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 9.47-kg watermelon at 28.2 ?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.

Explanation / Answer

Heat gained by soda = heat lost by watermelon 12 * 0.35 * 3800 * ( T-4.93) = 6.16 * 4180 * ( 24.5 -T) solve the above equation T= 16.88 C
