Question

A metallic rod of cross-sectional area 9.0 cm2 and length 0.54 m, with the surface insulated to prevent heat loss, has one end immersed in boiling water and the other in ice-water mixture. The heat conducted through the rod melts the ice at the rate of 1 gm for every 33 sec. The thermal conductivity of the rod is

  1. 330 Wm–1 K–1    
  2. 60 Wm–1 K–1    
  3. 600 Wm–1 K–1    
  4. 33 Wm–1 K–1    

The correct answer is: 60 Wm–1 K–1
