A 9,100​-microfarad ​[mu​F] capacitor is charged to 22 volts​ [V]. If the capacitor is completely discharged through an iron rod 0.2 meters​ [m] long and​ one-quarter centimeter​ [cm] in​ diameter, resulting in 80​% of the stored energy being transferred to the rod as​ heat, how much does the temperature of the rod​ increase? Give your answer in kelvin​ [K].  

Data you may​ need:
Specific Gravity of​ iron: SG = 7.874
Specific heat of​ iron: CP = 0.450 ​J/(g K)
