A 50 gram sample of delicious pork rinds is
placed in an open, constant pressure calorime-
ter that contains 3000 grams of water. The
temperature of the water increases by 47°C
when the pork rinds are combusted. The heat
capacity of water is 4.184 J/g °C. Assume the
heat lost to the calorimeter itself or to the air
is negligible. Which of the following is correct
for the SYSTEM?



Answer :
