A walrus transfers energy by conduction through its blubber at the rate of 150 W when immersed in -1.00C water. The walrus’s internal core temperature is 37.0C, and it has a surface area of 2.00m. What is the average thickness of its blubber, which has the conductivity of fatty tissues without blood?
NEED ANSWER ASAP
At a temperature of 33.7 °C a 0.42-mm gap exists between the ends of the rods shown. At a later time when the temperature has reached 122.8°C, determine the change in length of the steel rod if L = 321.85 mm and M = 211 mm. Round off the final answer to four decimal places.
Water standing in the open at 32.2 Celsius evaporates because of the escape of some of the surface molecules. The vaporisation (539 cal/g) is approximately equal to En, where E is the average energy of the escaping molecules and n is the number of molecules per gram.
(a) Find E.
(b) What is the ratio of E to the average kinetic energy of H2O molecules, assuming the layer is related to the temperature in the same way as it is for gases?
