A chef is testing out a new set of iron cookware. He knows that iron has a specific heat of 445 J/kg°C. He heats a 2 kg iron skillet on a stove for 5 minutes and finds that the temperature of the iron skillet has increased by 250°C. What change in temperature will the Chef observe when he heats his 4 kg iron skillet on the same stove for the same amount of time?
