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.
The higher the resistance, the lower the flow of electrons. This resistance causes a certain amount of heat to be generated in the circuit. The reason that a hair dryer blows hot air, for example, is because of resistance in the internal wiring that produces heat. And it is resistance in the tiny wires of an incandescent light bulb that causes it to heat up and glow with light.
