In a material processing experiment conducted aboard the space shuttle, a coated niobium sphere of 10 - mm diameter is removed from a furnace at 900°C and cooled to a temperature of 300°C. Although properties of the niobium vary over this temperature range, constant values may be assumed to a reasonable approximation, with rho = 8600 kg/m3, c = 290 J/kg middot K, and k = 63 W/m middot K.
