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.
Heat is the flow of energy from a high temperature location to a low temperature location. This flow of energy is always associated with changes in the system and the surroundings. There can be changes in the temperature, changes in the state of matter and changes that result from the doing of work.hat can be said of the object can also be said of the surroundings. The release or absorption of energy in the form heat by the surroundings is often associated with a temperature change of the surroundings.
