Two ends of a conducting rod of varying cross-section are maintained at `200^(@)C` and `0^(@)C` respectively. In steady state:

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

The temperature of the two ends A and B of a rod of length 25cm and circular cross section are 100^(@)C and 0^(@)C respectively In the steady state, find the temperature at a point 10cm from the end B (ifnore loss of heat from curved surface of the body) ?

The ends of copper rod of length 1 m and area of cross section 1cm^(2) are maintained, at 0^(0)C and 100^(0)C , and steady state achieved. At the centre of rod, there is a source of heat of 25W. The thermal conductivity of copper is 400W/mK

A rod of length L and uniform cross-sectional area has varying thermal conductivity which changes linearly from 2K at end A to K at the other end B . The ends A and B of the rod are maintained at constant temperture 100^(@)C and 0^(@)C , respectively. At steady state, the graph of temperture : T=T(x) where x= distance from end A will be

Two rods of similar area of cross section and length are joined as shown in the figure. The ratio of their thermal conductivity is 2:3. The free ends are maintained at 100^(@)C and 0^(@)C respectivley. THE temperature at junction in steady state is
