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).

1.	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).
