Basically, this problem asks you to convert kilocalories (kcal) to kilojoules (kJ). Both are units of energy. To convert kcal to kJ, the equivalence is: 1 kcal = 4.184 kJ. Through dimensional analysis, the solution is as follows:
750 kcal * 4.184 kJ/1 kcal = 3,138 kJ
They try not to interfere or play any part j what happens rather they just look at it and see the results
I'm pretty sure it's called, "gravity". or gravy :)
oxidation due to where air hits it
