# determine the thermal conductivity of the foam

3.

A Styrofoam box has a surface area of 0.80m2 and a wall thickness of 2.0cm. The temperature of the inner surface is 5.0°C and the outside temperature is 25°C. If it takes 8.0h for 5.0kg of ice to melt in the container, determine the thermal conductivity of the foam. (Assume that the temperature of the ice is 0°C)
