Two rods A and B are of equal length. Each rod has the ends at temp `T_(1)` and `T_(2)` . What is the condition that will ensure equal rates of flow of heat through the rods A and B ?

Two rods A and B have lengths l_1 and l_2. Each rod has its ends at temperature T_1 and T_2 Radii fo cross section of the two rods are same. The condition for equal flow of heat through those two rods is (K_1, K_2 are thermal conductivities of two rods)

A metallic rod is continuously heated at its two ends, the flow of heat through the rod does not depend upon –

Two rods of the same length and areas of cross-section A_1 and A_2 have their ends at the same temperature. K_1 and K_2 are the thermal conductivities of the two rods. The rate of flow of heat is same in both the rods if-

Two rods P and Q of equal lengths have thermal conductivities K_(1) and K_(2) and cross-sectional areas A_(1) and A_(2) respectively. If the temperature difference across the ends of each rod is the same, then the condition for which the rate of flow of heat through each of them will be equal, is

Equal temperature difference exists between the ends of two metallic rods 1 and 2of equal length. Their thermal conduetivities are K_(1) and K_(2) and cross sectional areas are respectively A_(1) and A_(2) . The condition for equal rate of heat transfer will be-

If the end of metal rod is heated then the rate of flow the heat does not depend on

The ends of a metal rod are kept at temperatures theta_1 and theta_2 with theta_2gttheta_1 . The rate of flow of heat along the rod is directly proportional to

Two rods of same length and areas of cross section A_1 and A_2 have their ends at same temperature. If K_1 and K_2 are their thermal conductivities, C_1 and C_2 their specific heats and rho_1 and rho_2 are their densities, then the condition that rate of flow of heat is same in both the rods is

The heat is flowing through two cylinderical rods of same material. The diameters of the rods are in the ratio 1:2 and their lengths are in the ratio 2:1 . If the temperature difference between their ends is the same, the ratio of rates of flow of heat through them will be
