Two different metallic rods of the same length have their ends kept at the same temperatures $heta_1$ and $heta_2$ with $heta_2 > heta_1$. If $A_1$ and $A_2$ are their cross-sectional areas, $K_1$ and $K_2$ their thermal conductivities, the rate of heat flow is the same in both the rods. The condition for this is:

Temperature is a measure of:
