Question

The thermal conduction equation (shown below) shows the heat energy per unit time transferred across a material with thermal conductivity k that has a thickness I and cross section area

A. The temperature on either side of the material are T1 and T2. \frac{Q}{t}=k A \frac{T_{2}-T_{1}}{\Delta x} ) Get a metal pan and a ceramic dish (glass or a plastic container are also fine forthe dish). Make sure both pan and dish are at room temperature and place themside by side on a countertop. Get two ice cubes that are the same size, andsimultaneously place one on the pan and the other on the dish. For the data section of your report observe and record in a table how the two ice cubes look at 1 min, 5 min, and 10 minutes after placing them on the pan and dish. A few descriptive words for each observation are sufficient. At the end of the 10-minute mark, touch the side of the pan and the dish at a point located several inches from the ice cube. Does either the pan or the dish feel colder than its original room temperature at this location? Look up the thermal conductivity k values of the two materials in a list of common materials like this one. The metal pan is likely either steel or cast iron .Ceramic is essentially glass.
