One end of a metal rod is kept in a furnce. In steady state, the temperature of the rod

Two rods are connected as shown. The rods are of same length and same cross sectional area. In steady state, the temperature (theta) of the interface will be -

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.

Two ends of a rod of uniform cross sectional area are kept at temperature 3T_(0) and T_(0) as shown. Thermal conductivity of rod varies as k=alphaT , (where alpha is a constant and T is absolute temperature). In steady state, the temperature of the middle section of the rod is

One end of a rod of length 20cm is inserted in a furnace at 800K The sides of the rod are coverd with an insulating meterial and the other end emits radiation like a black boy The temperature of this end is 750K in the steady state The temperature of the surrounding air is 300K Assuming radiation to be the only imporatant mode of energy transfer between the surrounding and the open end of the rod, find the thermal conductivity of the rod Stefan's constant sigma = 6.0 xx 10^(8) W m^(-2) K^(-4) .

A rod is heated at one end as shown in figure. In steady state temperature of different sections becomes constant but not same. Why so? .

One end A of a metallic rod of length 10 cm is inserted in a furnace whose temperature is 827^(@)C . The curved surface of the rod is insulated. The room temperature is 27^(@)C . When the steady state is attained, the temperature of the other end B ofthe rod is 702^(@)C . Find the thermal conductivity ofthe metal. Stefan's constant = 5.67 xx 10^(-8)W m^(-2) K^(-4) .

One end of a rod length 20cm is inserted in a furnace at 800K. The sides of the rod are coved with an insulating material and the other end emits radiation like a blackbody. The temperature of this end is 750K in the steady state. The temperature of the surrounding air is 300K. Assuming radiation to be the only important mode of energy tranfer between the surrounding and the open end of the rod, find the thermal conductivity of the rod. Stefan constant sigmas=6.0xx10^(-1)Wm^(-2)K^(-4) .

Three identical rods are joined at point O as shown in the figure. In the steady state, fid the ratio of thermal current through rod AO and OC. ltBrgt
