    Two identical rectangular rods of metal are welded end to end in series between temperature 0^(o) C and 100^(circ) C and 10 J of heat is conducted (in steady state process) through the rod in 2.00 min . If 5 such rods are taken and joined as saown in the figure maintaining the same temperature difference between A and B , then the time in min in which 20 J of heat will flow through the rods is '(##CEN_KSR_PHY_JEE_C13_E01_014_Q03##)'

    Temperature difference of 120^(@)C is maintained between two ends of a uniform rod AB of length 2L. Another bent rod PQ, of same cross-section as AB and length (3L)/(2) , is connected across AB (See figure). In steady state, temperature difference between P and Q will be close to :

    Assertion : Heat is supplied at constant rate from one end of a conducting rod. In steady state, temperature of all points of the rod becomes uniform. Reason : In steady state, temperature of rod does not increase.
