The ends of a rod of uniform thermal conductivity are maintained at different (constant) temperatures. Afer the steady state is achieved:

Two ends of area A of a uniform rod of thermal conductivity k are maintained at different but constant temperatures. At any point on the rod, the temperature gradient is (dT)/(dl) . If I be the thermal current in the rod, then:

The two ends of a uniform rod of thermal conductivity k are maintained at different but constant temperatures. The temperature gradientat any point on the rod is (d theta)/(dl) (equal to the difference in temperature per unit length). The heat flow per unit time per unit cross-section of the rod is l then which of the following statements is/are correct:

When two ends of a rod wrapped with cotton are maintained at different temperatures and after some time every point of the rod attains a constant temperature, then

The ends of a metal rod of length 40 cm are maintained at temperatures 100^(@)Cand20^(@)C respectively. At steady state condition, the temperature at a point at a distance 30 cm from the hot end of the rod is

Three rods of same dimensions have thermal conductivity 3K,2K and K They are arranged as shown in Then the temperature of the junction in steady state is .
