What is density?
Density is a physical characteristic, and calculates of mass per unit of volume of a material or substance. It is a measurement of the quantity of matter in a given volume of something.
The higher an object's density, the higher it's mass per unit of volume. The average density of an object equivalent its total mass divided by its total volume. A denser object (like iron) will have less volume than an equal mass of some less dense substance (like water).
When a physical property such as charge exists in discrete "packets" rather than in continuous amounts, the property is said to be: a) Discontinuous b) Abrupt c)

kelvin; K (after Lord Kelvin, 1824-1907): The basic SI unit of thermodynamic temperature explained as 1/273.16 of the thermodynamic temperature of the triple point of water.
How can electricity make magnetic fields? In 1820, Oersted discovered that an electric current can produce a magnetic field. He happened to notice a compass move when he conn
