Water is boiling in an aluminum pan placed on an electrical element on a stovetop. the pan has a bottom that is 0.800 cm thick and 14.0 cm in diameter. aluminum thermal conductivity is 220 w/(m oc). in every second, 1.2 g boiling water evaporates. the latent heat of vaporization for water is 2.26 × 106 j/kg. (a) how much heat is transfered to the boiling water in one second?

Explanation:

The given data is as follows.

    Thickness = 0.8 cm =    (As 1 m = 1000 cm)

    Diameter = 14.0 cm,   Conductivity =

    mass = 1.2 g,       L =

Now, we will calculate the heat of vaporization for water as follows.

               Q = mL

           Q =

           Q = 1808 J

So, rate of heat transfer in 1 sec  will be as follows.

        = 1808 J/s

Thus, we can conclude that 1808 J/s heat is transfered to the boiling water in one second.
