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.
