An insulated container is filled with mixture of water & ice at 0°C. Another container is filled with water that is continuous boiling at 100°C. In a series of experiments, the containers are connected by various thick rods that pass through the walls of the containers. The rod is insulated in such a way that there is no heat loss to surroundings. In experiment 1, a copper rod is used and the ice melts in 20 min. In experiment 2, a stell rod is used and ice melts in 60 min. How long would it take to melt the ice if the two rods are used in series given ans in …..× 10 min.
