Suppose you stand with one foot on ceramic flooring and one on a wool carpet, making contact over a 71.2 cm2 area with each foot. Both the ceramic and the carpet are 2.00 cm thick and are 10.0°C on their bottoms. At what rate must each foot supply heat to keep the top of the ceramic and carpet at 33.0°C? The thermal conductivity of ceramic is 0.84 J/(s · m · °C) and that of wool is 0.04 J/(s · m · °C).
