Lou has patented a cooking timer, which he is marketing as "Nature's Way: Taking You Back To Simpler Times." The timer consists of a 28-cm copper rod having a 5.0-cm diameter. Just as the lower end is placed in boiling water, an ice cube is placed on the top of the rod. When the ice melts completely, the cooking time is up. A special ice cube tray makes cubes of various sizes to correspond to the boiling time required. What is the cooking time when a 30-g ice cube at –5.0^oC is used?
