A skillet made of Iron (Fe) weighing 1.8 kg is heated on a stove to a temperature of 202 degrees C. If the skillet is removed from the stove and allowed to cool to room temperature (21 degrees C), how much heat must be removed from the skillet. The specific heat of Iron is 0.449 J/(g. degrees C).
1 answer
q = heat removed = mass Fe x specific heat Fe x (Tfinal-Tinitial)
