1) A large punch bowl holds 3.10 kg of lemonade (which isessentially water) at 21.0 degs C. A 6.00Ã10-2 kg ice cube at -13.0degs C is placed in the lemonade. What is the final temperature ofthe system? Ignore any heat exchange with the bowl or thesurroundings.
____=degrees C
2)An 800-g iron block is heated to 390 degrees C and placed in aninsulated container (of negligible heat capacity) containing 35.0 gof water at 25.0 degrees C. What is the equilibrium temperature ofthis system? The average specific heat of iron over thistemperature range is 560 J/(kg*K) .
____=degrees C
