Ice Cube Melting

A 500.0 gram ice cube (initially at 0.00 oC) is placed in a Styrofoam box with wall thickness 1.0 cm and total surface area of 6.0 x 102 cm2. If the air surrounding the box is at 20.0 oC and after 4.0 hours the ice is completely melted, what is the conductivity of the Styrofoam material?

Solution Summary

This solution defines thermal conductivity and states the equation which is calculated for the Styrofoam cup containing the ice cube. All steps are shown with brief explanations.
