A pоlаr beаr plunge (оr swim) is аn event held (usually during the winter) where participants enter a bоdy of very cold water. In Canada, polar bear swims are usually held on New Year's Day to celebrate the new year. At Scott Base in Antarctica, naked polar bear plunges are an annual tradition. Calculate the rate of heat conduction out of a 56.0 kg man whose surface area is 1.57 m2. The water (and therefore his skin) is at a temperature of 1.26 °C and his internal temperature is 37.2 °C. The thickness of his tissues separating these temperature regions is 1.26 cm.
