(a) Calculate the rate of heat conduction (in W) through a double-paned window that has a 5.00 m2 area and is made of two panes of 0.700 cm thick glass separated by a 1.00 cm air gap. The inside surface temperature is 17.0°C, while that on the outside is −20.0°C. (Hint: There are identical temperature drops across the two glass panes. First find these and then the temperature drop across the air gap. This problem ignores the increased heat transfer...

Given human body core temperature=37C, skin surface temperature=33C, surface area of body=1.5m^2, and average thickness=1.0cm. Thermal conductivity is 0.2J/(s*m*degree). If one takes into account heat conduction through the skin as the only mechanism for energy dissipation from the body how long would it take to dissipate all the energy contained in a food consisting of 140 Calories?

(a) What is the rate of heat conduction (in W) through the 2.00 cm thick fur of a large animal having a 1.30 m2 surface area? Assume that the animal's skin temperature is 30.0°C, that the air temperature is −6.50°C, and that fur has the same thermal conductivity as air. (Assume the thermal conductivity of air is 0.023 J/(s · m · °C).) W (b) What food intake (in kcal) will the animal need in one day to replace this...

Consider
the rate of heat conduction through a double-paned window that has
a 1.45-m2 area and is made of two panes of
0.715-cm-thick glass separated by a 1.25-cm air gap. You can ignore
the increased heat transfer in the air gap due to convection.
Calculate the rate of heat conduction through this window, in
watts, given that the inside surface temperature is 15.0°C, while
the outside temperature is -10.0°C. Make the assumption that the
temperature differences across the two glass...

The rate of heat conduction out of a window on a winter day is rapid enough to chill the air next to it. To see just how rapidly windows transfer heat by conduction, calculate the rate of conduction in watts through a 3.00 m2 window that is 0.645 cm thick if the temperatures of the inner and outer surfaces are 5.00°C and -10.0°C, respectively. This rapid rate will not be maintained—the inner surface will cool, and even result in frost...
