During light activity, a 70-kg person may generate 200 kcal /h. Assuming that 20% of this goes into useful work and the other 80% is converted to heat, calculate the temperature rise of the body after 1.00 h if none of this heat were transferred to the environment.

During light activity, a ( m=70kg ) person maygenerate ( P=200kcal/h). Assuming that 20% of this energy is used for productive purposes and the remaining 80% is converted to heat,
Total heat per hour (Q)=200,000cal
The heat for rise the temp. Q=80% of 200000=1.6105 cal
The temperature rise of the body after 1.00 h
Dt=Qmc
where c is the spec.heat capacity of humenbody
Use the above data, find the increase temperature.
