Vaporizing a Human Conditions https://www.thoughtco.com/chemical-composition-of-the-human-body-603995 Okay, First off. To vaporize a human thoroughly at once, let's assume the temperature change is 1800┬░F or 982.22┬░C https://www.cremationresource.org/cremation/how-is-a-body-cremated.html Average body temperature is 97.7┬░F-99.5┬░F or 36.5┬░C-37.5┬░C, giving us the average of 98.6┬░F or 37┬░C. https://en.wikipedia.org/wiki/Human_body_temperature So the temperature change is by 945.22┬░C http://endmemo.com/physics/specificheat.php https://en.wikipedia.org/wiki/Human_body_weight The average human is 62 kilograms. STEP I We will start with water. https://en.wikipedia.org/wiki/Body_water 60% of human mass is water, or 37.2 kilograms. http://www.engineeringtoolbox.com/water-thermal-properties-d_162.html The heat capacity of water is 4.1813 kilojoules per kilogram Plugging the values into this calculator Specific Heat energy is 147023640 joules We will use this calculator to find the latent heat of the water, which says water has a latent heat of 2264.705 kJ/kg. Plugging in the mass of water gives us 84,247,026 joules Adding these two values together we get 231,270,666 J STEP II https://www.itis.ethz.ch/virtual-population/tissue-properties/database/heat-capacity/ Average amount for body fat is 2.348 kilojoules per kilogram Fat seems to be 17% of body mass, or 10.54 kilograms going by the numbers shown Plugging it into the specific heat energy calculator, we get 23,392,229 joules STEP III Protein makes up 16% of body mass, which means it makes up 9.92 kilograms of the body https://www.itis.ethz.ch/virtual-population/tissue-properties/database/heat-capacity/ Muscle has a heat capacity of 3.421 kilojoules per kilogram Plugging it into the specific heat energy calculator, we get 32,077,288 J. STEP IV For minerals, it makes up 6% of body mass, or 3.72 kilograms. We will use bone for this, specifically cortical bone, which is 1.313 kilojoules per kilogram. https://itis.swiss/virtual-population/tissue-properties/database/heat-capacity/ We get 4,616,795 J STEP V Carbohydrates make up merely 1% of human weight, or 0.62 kilograms https://www.researchgate.net/post/W...s_for_liquid_amorphous_glass_and_solid_states Heat energy of sugar (carbohydrate) is 1.255 kilojoules per kilogram. We get 735,476 joules Conclusion Adding them together, we get 292,092,454 joules or 0.0698 tons of TNT Small Building level Reducing a human to char In the case of reducing humans to just dry bone fragments instead of fully vaporizing them, crematoriums recommend a minimum starting temperature of 1400┬░F or 760┬░C. https://www.cremationresource.org/cremation/how-is-a-body-cremated.html Conditions https://www.thoughtco.com/chemical-composition-of-the-human-body-603995 Average body temperature being 98.6┬░F or 37┬░C, https://en.wikipedia.org/wiki/Human_body_temperature The temperature change is by 723┬░C http://endmemo.com/physics/specificheat.php https://en.wikipedia.org/wiki/Human_body_weight The average human is 62 kilograms STEP I We will start with water. https://en.wikipedia.org/wiki/Body_water 60% of human mass is water, or 37.2 kilograms. The heat capacity of water is 4182 joules per kilogram at 20 ┬░C Plugging the values into this calculator Specific Heat energy is 112,477,399.20 joules We will use this calculator to find the latent heat of the water, which says water has a latent heat of 2264.7057 kJ/kg. Plugging in the mass of water gives us 84,247,052.04 joules Adding these two values together we get 196,724,451.20 J STEP II https://www.itis.ethz.ch/virtual-population/tissue-properties/database/heat-capacity/ Average amount for body fat is 2.348 kilojoules per kilogram Fat seems to be 17% of body mass, or 10.54 kilograms going by the numbers shown Plugging it into the specific heat energy calculator, we get 17,892,746.16 joules STEP III Protein makes up 16% of body mass, which means it makes up 9.92 kilograms of the body https://www.itis.ethz.ch/virtual-population/tissue-properties/database/heat-capacity/ Muscle has a heat capacity of 3.421 kilojoules per kilogram Plugging it into the specific heat energy calculator, we get 24,535,959.36 J. STEP IV For minerals, it makes up 6% of body mass, or 3.72 kilograms. We will bone for this, specifically cortical bone, which is 1.313 kilojoules per kilogram. https://itis.swiss/virtual-population/tissue-properties/database/heat-capacity/ We get 3,531,392.28 J STEP V Carbohydrates make up merely 1% of human weight, or 0.62 kilograms https://www.researchgate.net/post/W...s_for_liquid_amorphous_glass_and_solid_states Heat energy of sugar (carbohydrate) is 1.255 kilojoules per kilogram. We get 562,566.30 joules Conclusion Adding them together, we get 243,247,115.30 joules or 0.058137456 tons of TNT (Small Building level) |
