QUESTION 9 An energy bar contains approximately 16.7 grams of protein. Given that the energy content per gram of protein is approximately 4.0 Calories, that is the total energy content of the energy bar in joules? (1 calorie = 4.184 J) QUESTION 10 A 16.2 gram bar of iron initially at 72.5 "c, was added to 87.9 grams of water initially at 17.9 "C. Given that the specific heat of iron is 0.444 J/g'C and that of water is 4.184 J/g*C, what will be the final temperature of either of the two substances?
