Granites can be predominantly white, pink, or gray in color, depending on their mineralogy. The word granite comes from the Latin granum, a grain, in reference to the coarse-grained structure of such a holocrystalline rock.By definition, granite is an igneous rock with at least 20% quartz and up to 65% alkali feldspar by volume.ranites can be predominantly white, pink, or gray in color, depending on their mineralogy.

How does electricity produce heat, and where do the electrons go? When electrons flow through a conductor it is subject to resistive loss, which has the unfortunate capability of producing heat from this current, leaving us with less current in the other end of the conductor opposite to the power source.
Resistors work by converting electrical energy to heat energy; in other words, they get hot when electricity flows through them. But it's not just resistors that do this. Even a thin piece of wire will get hot if you force enough electricity through it.
