A brass boiler has a base area of 0.15 m2 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 boiler. Thermal conductivity of brass = 109 J s ^-1m^- 1K^-1 , Heat of vaporisation of water = 2256 xx 10^3 J kg^-1 .

The solubility product of salt AB is 1 xx 10^(-8) In a solution in which concertration of A is 10^(-3) M . The AB will precipitate when the concentration of B becomes.
