Calculate the rate of heat conduction out of the human body, assuming that the core internal temperature is $37.0^{\circ} {C}$ the skin temperature is $34.0^{\circ}{C},$ the thickness of the tissues between averages $1.00 {cm},$ and the surface area is 1.40 ${m}^{2}$

The rate of heat transfer is $84 \times 10^{3} \mathrm{W}$

in this question. We want to find out the rate of heat conduction on the human body. Uh, so we need to use the radio he conduction equation, which is Huberty equals. Okay, thermal conductivity times the area times change in temperature over thickness D. So in our case, we can look up k for fatty tissue, which is quoted as your point to Jules per second time's meter times to be silky. It's the area's given us 1.4 square meters. Tea, too eyes the difference on the skin. So is 37 degrees Celsius. T one is 30 or degree Celsius and were given a skin thickness of one centimeter to the same as your 10.1 meters. So that means Q Over T equals 0.2 jewels for second times. Media your attempts for your Celsius. It's the area four square meters times the change in temperature. 37 Money's 34 degree Celsius, divided by the thickness. Your points were one meters. So we're canceling the meter squared up here with the two meters down here, degree Celsius near left, with 84 jewels per second, which is the same as 84 watts
