In the steady state the two ends of a meter rod are at `30^(@)C` and `20^(@)C` the temperature at the `40^(th) cm` from the end at higher temperature is .

In steady state condition, the temperatures at the two ends of a metal rod of length 25 cm are 100^(@) C and 0^(@) C. Then temperature at a point 8cm from the hot end is

In steady state condition, the temperatures at the two ends of a metal rod of length 25 cm are 100^(@)Cand0^(@)C . Then temperature at a point 8 cm from the hot end is

In a steady state of heat conduction the temperature of the ends A and B of a rod 100cm long per 0^(@)C and 100^(@)C The temperature of the rod at a point 60cm distant from the end A is .

Heat is flowing through a rod of length 25.0 cm having cross-sectional area 8.80 cm^(2) . The coefficient of thermal conductivity for the material of the rod is K = 9.2 xx 10^(-2) kcal s^(-1) m^(-1) .^(@)C^(-1) . The Temperatures of the ends of the rod are 125^(@)C and 0^(@)C in the steady state. Calculate (i) temeprature gradient in the rod (ii) temperature of a point at a distance of 10.0 cm from the hot end and (iii) rate of flow of heat.

Two rods of same dimensions, but made of different materials are joined end to end to end with their free end being maintained at 100^(@)C and 0^(@)C respectively. The temperature of the junction is 70^(@)C . Then the temperature of the junction if the rods are inerchanged will be equal to T^(@)C Find T :
