How much heat is absorbed by a 67g iron skillet when its temperature rises from 14oc to 22oc?

Explanation:

The heat (thermal energy) absorbed by the iron skillet can be found using the following equation:

  (1)

Where:

is the heat

is the mass of the element (iron in this case)

is the specific heat capacity of the material. In the case of iron is

is the variation in temperature

Knowing this, lets rewrite (1) with these values:

 (2)

Finally:

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
