Briefly explain, how does a metallic rod heated at one end attain steady state ? Write the important features of steady state.

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

On what factors does the rate of heat conduction in a metallic rod in the steady state depend? Write the necessary expression and hence define the coefficient of thermal conductivity. Write its units and dimensions also.

Assume that the thermal conductivity of copper is twice that of aluminium and four times that of brass. Three metal rods made of copper, aluminium and brass are each 15 cm long and 2 cm in diameter. These rods are placed end to end, with aluminium between the other two. The free ends of the copper and brass rods are maintained at 100^@C and 0^@C respectively. The system is allowed to reach the steady state condition. Assume there is no loss of heat anywhere. When steady state condition is reached everywhere, which of the following statement is true?

The system is allowed to reach the steady state condition. Assume there is no loss of heat anywhere. Under steady state condition the equilibrium temperature of the copper aluminium junction will be

In the steady state of temperature the flow of heat across the body depends :

Figure shows a network of capacitor and resistances. . 3V Potentials of some of the points are given. The energy (U) stored in the capacitor at steady state and the heat (H) dissipated in 1Omega resistor at steady state are

The lengths and radii of two rods made of same material are in the ratios 1 : 2 and 2 : 3 respectively. If the temperature difference between the ends for the two rods be the same, then in the steady state, the amount of heat flowing per second through them will be in the ratio

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.
