A brass boiler has a base area of `0.15 m^(2)` and thickness `1.0` cm. It boils water at the rate of `6.0` kg/min when placed on a gas stove. Estimate the temperature of the part of the flame in contact with the boller. Thermal conductivity of brass ` = 109 J s^(-1) m^(-1) K^(-1)`, Heat of vaporisation of water `= 2256 xx 10^(3) J kg^(-1)`.
