- The exterior walls of a house have a total area of 194 m2 and are at 12.4°C and the surrounding air is at 7.4° C. Find the rate of convective cooling of the walls, assuming a convection coefficient of 2.9 W/(m2·°C). Since you're looking for the rate of cooling, your answer should be entered as positiveSuppose a walrus transfers energy by conduction through its blubber at the rate of 125 W when immersed in -1.25°C water. The walrus’s internal core temperature is 37.0°C, and it has a surface area of 1.85 m2. Chart attached. What is the average thickness of its blubber, in centimeters, which has the conductivity of fatty tissue?When a material changes phase - liquid, solid, gas- heat exchange is required. This heat is called the Latent heat. is the equation where L is the Latent heat and is material specific. How much heat is required to take water (mass of .55 kg) from -20 to 20 C? L for ice to water is 33.5 * 104 J/kg. the specific heat of ice is 2090 J/(kg*C).and for water is 4186 J/(kg*C).

Answer format is the number Eice/Ewater = (2 significant figures) Latent Heat of Fusion of Water: 335, 000 J/kg Specific Heat Capacity of Water: 4186 J/kg/\deg CA hot steel plate with a surface area of 2.17 m2 and a constant surface temperature of 165°C is exposed to ambient air at 24°C. If the convection heat transfer coefficient is 15.4 W/m2· K, what is the rate of heat transfer (in W) from the plate to the air [round your final answer to zero decimal places]?An aluminum pizza pan of mass 1.67 kg is initially at a room temperature of 18.5 degrees Celsius. The pan is then placed in the oven to be used for cooking a pizza. Once inside the oven, the pan reaches a temperature of 275 degrees Celsius. If the heat trasferred from the over to the aluminum pan is 387000 J, find the value of the specific heat capacity of aluminum.
