How much heat is absorbed by a 45g iron skillet when its temperature rises from 6oc to 21oc?

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:

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.
