A 50 cm long rod is half aluminum and half copper. The aluminumend is in boiling water. The end of an aluminum rod (50 cm long) ismaintained at 100 C by immersing in a pot of boiling water and theother end at 00C by an ice-water mixture. If the cross-sectionalarea of the rod is 1.3 cm2, how much will the rod melt in 20 min?What will be the steady temperature at the Al-Cu junction?
