What temperature would be reached during spontaneous human combustion?
What temperature (OC) would be reached if all of the burnable material were to simultaneously ignite? Assume starting temperature of 37°C. Energy value in Energy value in kilojoules (kJ) kilocalories (kcal) per gram per gram Mixed lipids 9.3-9.5 39-40 4.0-4.1 Mixed carbohydrates 17 Hydrated glycogen 1.1 4.6 Mixed proteins 4.3-4.8 18-20 calorie: quantity of heat required Heat produced per unit of O2 to raise the temperature of 1 consumed (U/mL O2) Foodstuff gram of water by 1°C. 21.1 Carbohydrates Body composition 149 lb person): Lipids 19.8 12kg protein Proteins 18.7 10kg fat. 4kg minerals What's the 1kg nucleic acid temperature? 0.5 kg carbohydrates 40 kg H20Explanation / Answer
Answer:
Body composition ( 149 lb person ):
a) It has given that, 1 gram of protein has energy value = 4.3 - 4.8 (Avg 4.5) kilo calorie
The total protein present in the body (12kg) has energy value = 12 X 4.5 = 54 kcal
b) 1 gram of lipids has energy value = 9.3 - 9.5 ( avg 9.4) kcal
The total lipids present in the body (10kg) has energy value = 94 kcal
c) 1 gram of carbohydrates has energy value = 4.1 kcal
The total carbohydrates present in the body (0.5kg) has energy value = 4.1 X 0.5 = 2.05 kcal
Total energy value in the body = 94 + 54 + 2.05 = 150.05 kcal = 150050 cal
It has given that,
1 calorie of heat required to raise the temperature of 1 gram of water by 1oC
There are 40 kg of water present in the body
So, the amount of heat required to raise 40 kg of water by 1oC = 40 cal
So, in 40 cal of heat, the temperature of the body water raised by 1oC
Therefore, in 150050 cal of heat (total body energy value) , the temperature of body water raised by = 3750 degree celcius (approximate).
As the starting temperature of the body is 37oC, temperature would be reached during spontaneous human combustion is 3787oC.
