Answer:
The furnace releases 1757280 J
Explanation:
We will do the conversion on two steps:
1- convert the kcal to cal
2- convert the cal to J
Step 1: converting kcal to cal
1 kcal is equivalent to 1000 cal. Therefore:
420 kcal is equivalent to 420*1000 = 420000 cal
Step 2: converting cal to J
We are given that:
<span>1 cal = 4.184 J
</span>Therefore:
420000 cal is equivalent to 420000 * 4.184 = 1757280 J
Hope this helps :)
