A team of students tests a material for its thermal conductivity (k).  After 20 minutes in a heat box, the temperature is 48° C inside the box and 28° C on top of the material.  The following data is true about this test: Area of material = .0225 m2      Thickness of material = .0127 m        Light bulb = 25 W What is the thermal conductivity constant for the material?  Calculate the amount of energy transferred through the material.  Determine the R-value of the material.  Based on your calculations, would the material be a reasonable choice for home insulation? Yes of No

When energy travels from one object to another it is said to have undergone heat transfer. Heat transfer is nothing but the transfer of thermal energy or internal energy from one thing to another, like e.g., when a vessel with water, kept on top of a burner, heats up because of the flame underneath it.
