Answer» Figure shows three containers. The rightmost container contains water (heat capacity $5 c a l /^{\circ} C$ ), initially at temperature $100^{\circ} C$ . The middle container contains water maintained at $80^{\circ} C$ with the help of a heater. The container at the left hand side contains ice at $0^{\circ} C$ . There are two heat conducting rods $A$ and $B$ both having thermal resistance equal to $10^{\circ} C s/cal$ . Disregard any heat loss in the surrounding. Initially, what is the power of heater required to maintain the temperature of middle container at $80^{\circ} C$ ?
