Final answer:The average adult human burns 2,000 kcal per day, which is equivalent to 8,368 kJ/day or approximately 348 kJ/hour.Explanation:To convert from kcal per day to kJ per hour, we need to use the conversion factor that 1 kcal = 4.184 kJ. Since theaverage adult human burns2,000 kcal per day, we can multiply this by the conversion factor to get the rate in kJ per day. Then, we divide this by 24 to get the rate in kJ per hour.2,000 kcal * 4.184 kJ/kcal = 8,368 kJ/day8,368 kJ/day / 24 hours = 348 kJ/hourTherefore, the correct answer is A) 8.37 kJ/hour.Learn more about Energy conversion here:brainly.com/question/33439849#SPJ11...
