A human body transports heat energy from the interior tissues,at temperature 37.0 $\circ$ C,to the skin surface at temperature 27.0 $\circ$ C.If the skin area is 1.5 m² and its thickness is average 2.4 mm,what is the rate energy is transferred through the skin? Assume and effective thermal conductivity of skin of 0.022 W/(m * K)

The rate of energy transfer through the skin can be calculated using the formula for heat conduction: $Q/t = kA(T_{\text{hot}} - T_{\text{cold}})/d$, where $Q/t$ is the rate of heat transfer, $k$ is the thermal conductivity, $A$ is the area through which heat is transferred, $T_{\text{hot}} - T_{\text{cold}}$ is the temperature difference, and $d$ is the thickness of the material. Plugging in the given values: $k = 0.022 \, \text{W/(m}\cdot\text{K)}$, $A = 1.5 \, \text{m}^2$, $T_{\text{hot}} - T_{\text{cold}} = 37.0 - 27.0 = 10.0 \, \text{°C}$, and $d = 2.4 \, \text{mm} = 0.0024 \, \text{m}$, we get $Q/t = 0.022 \times 1.5 \times 10 / 0.0024 = 137.5 \, \text{W}$, which rounds to approximately 140 W.
