A brass bar is joined at one end to a 70 cm copper bar and at the other end with boiling water at 1 atm. In order to achieve conductive heat transfer, the copper-free end is brought into contact with a mixture of water and ice also at 1 atm. Both bars have a cross sectional area of 0.00500 m2. The sides of the rods are insulated, so there is no heat loss to the surroundings. If after 5 minutes 50 g of ice melts, find the length of the brass bar.
