If a person's body has a specific heat equal to that of water and produces 6.28 kJ per min per kilogram of body mass, what is the rate of increase in body temperature in °C per min if the person is suddenly made adiabatic?
*Rumor has it that Frankenstein's monster was brought to life by charging it with 1.00 kW of power for 2.00 h, after which it operated with an efficiency of only 25.0%.
a. If the monster consumed its charged energy at a rate of 1.30 MJ/h, how long before it needed to be recharged again?
b. If the monster had a mass of 100. kg, what would be its mean metabolic rate in MJ/d if it were a normal mammal?
