While running, a 66 kg student generates thermal energy at arate of 1500 W. To maintain a constant body temperature of 37.0 ∘C,this energy must be removed by perspiration or othermechanisms.
1.If these mechanisms failed and the heat could not flow out ofthe student's body, for what amount of time could a student runbefore irreversible body damage occurred? (Protein structures inthe body are damaged irreversibly if the body temperature risesto 44.0 ∘C∘C or above. The specific heat capacity ofa typical human bodyis 3480 J/(kg⋅K)J/(kg⋅K), slightly less than that ofwater. The difference is due to the presence of protein, fat, andminerals, which have lower specific heats.)
