How much heat is absorbed by a 75g iron skillet when it’s temperature rises from 5c to 20c?

Explanation:

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

  (1)

Where:

is the heat  (absorbed)

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:
