Water has a specific heat of 4.187 kilojoules per kilogram-Kelvin.

Using the formula Q=m*c*dT, we can calculate thermal energy in Joules (Q), based on mass in kilograms (m), specific heat in kJ/kg*K (c), and change in temperature (dT)

m is already established as 81 kg.

c is the specific heat, 4.187 kJ/kg*K

dT is 310.15 Kelvins, because we're wanting

*all*the thermal energy in the person.

Q = 81

Q = 81 * 4.187 kJ * 310.15-->Arithmetic

Q = 105186.44205 kJ

How much energy is a hundred thousand kilojoules?

- According to Wolfram Alpha: 79% of the energy in a gallon of gas.
- 1.7 times the amount of energy needed to accelerate 1 kg to escape velocity from Earth (ignoring drag)
- 2.5 times the energy consumed daily by <ichael Phelps while training for the Olympics
- Equivalent to annihilating 1.2 micrograms of matter as per E=mc
^{2}

If you account for the calories contained in bodily tissue, it becomes a much bigger number, but I'm not doing the math for that unless somebody asks me.
