A $1000-$W iron is left on the ironing board with its base exposed to the air at $23C.$ The convection heat transfer coefficient between

the base surface and the surrounding air is $25\mathrm{.}00\frac{W}{m^2}.C.$ If the base has an emissivity of $0\mathrm{.}4$ and a surface area of $0\mathrm{.}02m^2,$

determine the temperature of the base of the iron. $($Round the final answer to three decimal places.$)$

Consider the value of Stefan$-$Boltzmann constant to be $5\mathrm{.}67{10}^{-8}\frac{W}{m^2}{K}^4.$

The temperature of the base of the iron is

$C.$
