A small copper ball of 5 mm diameter at 500 K is dropped into an oil bath whose temperature is 300 K. For copper, the thermal conductivity is 400 W/m-K, density is 9000 kg/m3 and specific heat is 385 J/kg-K. If the heat transfer coefficient is 250 W/m2-K and lumped analysis is assumed to be valid, the rate of fall of the temperature of the ball at the beginning of cooling will be
