Helium
|
A colorless, odorless inert gaseous element occurring in natural gas and with radioactive ores. It is used as a component of artificial atmospheres and laser media, as a refrigerant, as a lifting gas for balloons and as a superfluid in cryogenic research. Atomic number 2; atomic weight 4.0026; boiling point -268.9ºC; density at 0ºC 0.1785 gram per liter.

Kelvin
|
1. A unit of absolute temperature equal to 1/273.16 of the absolute temperature of the triple point of water. One Kelvin degree is equal to one Centigrade degree.
2. Kelvin A temperature scale in which zero occurs at absolute zero and each degree equals one kelvin. Water freezes at 273.15 K and boils at 373.15 K.

Magnet
|
An object that is surrounded by a magnetic field and that has the property, either natural or induced, of attracting iron or steel.

|
Nitrogen
|
A nonmetallic element that constitutes nearly four-fifths of the air by volume, occurring as a colorless, odorless, almost inert diatomic gas, N2, in various minerals and in all proteins and used in a wide variety of important manufactures, including ammonia, nitric acid, TNT and fertilizers. Atomic number 7; atomic weight 14.0067; melting point -209.86ºC; boiling point -195.8ºC; valence 3, 5.

Physics
|
The science of matter and energy and of interactions between the two, grouped in traditional fields such as acoustics, optics, mechanics, thermodynamics, and electromagnetism, as well as in modern extensions including atomic and nuclear physics, cryogenics, condensed matter physics, particle physics, and plasma physics. |

Resistance
|
Electricity. The opposition of a body or substance to current passing through it, resulting in a change of electrical energy into heat or another form of energy.

|
Tesla
|
The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter. A typical refrigerator magnet has a flux density at its surface of 0.01 tesla.
