Question
One way to measure conduction constant ,k, is to make a closed container out of a material and put a heater inside the container. The heater maintains a constant difference in temperature on each side of the walls of the container.The heater has a surface area of 2.16 m^2 and the thickness of the walls is 3.90 cm.
The heater requires 60 W to maintain 40°C temperature difference on both side of the walls of the container. Find the conduction for the material.
b) What material is the container probably made of base on this table (see link)
