    IF YOU CANNOT SOLVE THEM ALL THEN PLEASE DONT SOLVE ANY. A hollow aluminum sphere, with an electrical heater in the center, is used in tests to determine the thermal conductivity of insulating materials. The inner and outer radii of the sphere are 0.15 and 0.18 m, respectively, and testing is done under steady-state conditions with the inner surface of the aluminum maintained at 250°C. In a particular test, a spherical shell of insulation is cast on the outer surface...

    can you write a conclusion for the report? Thermal Conductivity Lab Introduction The objective of this lab is to explore the thermal conductivity of various materials using Fourier’s Law and a steady state system. Certain materials are more effective heat conductors than others. The effectiveness of a given material at heat conduction is influenced by many factors, including density, molecular structure, and chemical composition. Fourier’s Law takes these factors into account to calculate Q, or the joules per second rate...
