According to Stefan's law of radiation, a black body radiates energy σT⁴ from its unit surface area every second, where T is the surface temperature of the black body. A nuclear weapon may be thought of as a ball of radius 0.5 m. When detonated, it reaches a temperature of 10⁶ K and can be treated as a black body.If surrounding has water at 30 C° , how much water can 10% of the energy produced evaporate in 1 s? [L_w=4186.0 J/kg K andL_v=22.6× 10⁵J/kg ]
