A stove top heating element (electric heating) gives off heat at a rate of 2250 W. If you place an iron skillet that's full of water on this heating element then how long would it take to heat both up from 22°C to 83°C? The iron skillet has a mass of 1.5 kg and a specific heat of 450 J/kg • K. The water has a mass of 1.1 kg and a specific heat of 4186 J/kg • K.

SETUP In today’s lab we will measure specific heat using a calorimeter. A calorimeter consist of a small metal cup inside a larger metal container, with a lid.  The cups are thermally separated from each other by means of air and a wooden ring, thus reducing the thermal conduction to a minimum. To keep track of how much water etc. we have, the whole calorimeter will be placed on a digital scale. Make sure to zero the scale before you place...
