QUESTION:
The enthalpy of combustion of a gallon (3.8 liters) of gasoline is about 31,000 kcal. The enthalpy of combustion of an ounce (28 g) of corn flakes is about 100 kcal. Compare the cost of gasoline to the cost of corn flakes, per calorie.
ANSWER:Solution
Step 1
The enthalpy of combustion of one gallon ( 3.8 L) of gasoline =31000 k cal
=31106 cal
The enthalpy of combustion of one ounce (28g)of corn flakes = 100 k cal
= 10104 cal
