Answer :
Final answer:
If the release of energy is 39.4 kJ, it releases approximately 9.42 kilocalories.
Explanation:
Energy can be measured in various units, such as joules, calories, and kilocalories. When converting from kilojoules to kilocalories, we can use the conversion rate where 1 kcal equals 4.184 kJ. To find out how many kilocalories are equivalent to 39.4 kJ, the calculation involves dividing 39.4 kJ by 4.184 kJ/kcal, resulting in approximately 9.42 kcal. It is crucial to remember that in dietary terms, when we mention 'calories', we are often referring to kilocalories, with Calories (with a capital C) being equivalent to kilocalories in these contexts.

By using unit conversion, the energy released in kilocalories is 9.42 kcal.
We need to know about unit conversion to solve this problem. There are several energy units which able to explain how much the energy is such as calories and joule. The energy unit can be converted to another unit by unit conversion. The unit conversion of calorie to joule is
1 cal = 4.184 joule
From the question above, we know that
E = 39.4 kJ
By using the unit conversion, we can convert the energy into calorie
E = 39.4 kJ
E = 39.4 x 10³ J
E = 39.4 x 10³ / 4.184 cal
E = 9.42 x 10³ cal
E = 9.42 x 10³ /10³ kcal
E = 9.42 kcal
Hence, the energy released in kilocalories is 9.42 kcal.
