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

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

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:
