Question: The average thermal conductivity of the walls (including windows) and roof of a house in the figu... The average thermal conductivity of the walls (including windows) and roof of a house in the figure shown below is 4.8 10-4 kW/m Â· Â°C, and their average thickness is 21.5 cm. The house is heated with natural gas, with a heat of combustion (energy given off per cubic meter of gas burned) of 9,300 kcal/m 3.
Each material's thermal conductivity is determined by a constant, Î», calculated as: Î» = (Q x L) / (A x t x Î T) where Q is heat, L is the thickness of the surface, A is the surface area, t is time, and ÎT is the difference in temperature. A material's thermal conductivity is a fundamental property. Those materials with high thermal conductivity will transfer heat rapidly, either by receiving heat from a hotter material or by giving heat to a colder material. On the contrary, materials with low thermal conductivity act as thermal insulators, preventing the transfer of heat.
