Question

Normal body temperature is regulated to be about 37 degree C. A body have a temperature plusminus 5 degree C (32-42 degree C) can be serious and even fatal. If your body has no way to dissipate heat, then your temperature will increase. Suppose you insulate your whole body so that no energy can enter or leave. If your metabolic rate (amount of energy expended while the body is at rest) is 100 W, then how long will it take for your body to rise 5 degree C? Let the specific heat of the body with a mass of 80 kg be 4.2 times 10^3 J/kg degree C. How long would you survive with this body weight?

Explanation / Answer

use the formula from heat

as Heat required = Q = m c dT

m is mass

c is specific heat

dT is change of temperature

alos Power = Q/t

so here 100 = 80 * 4.2*10^3 * 5/t

t = 16800 secs

t = 280 mins

t = 4.67 hrs
