The conducting abilities of water depends on the type of water or the purity of it. Pure water, that does not have any other elements in it is a better insulator of electricity than it is a conductor. The opposite holds true for things like salt water, because of the extra elements in it.
Uranium and Radon, the densest solid and gas respectively, are the best conductors of heat. The ability to conduct heat is called specific heat and is closely linked to density. The denser a material is, the closer its specific heat is to zero and the more easily it conducts heat.
Many metals, like silver, copper, gold and aluminum, are good thermal conductors. Thermal conductors are materials that heat passes through easily. Conduction, or the transfer of heat, can take place within a single material or between two objects.
Air is not a good conductor of heat, as it actually serves as an insulator when it is contained in an enclosed area. Air helps to prevent heat loss, instead of transferring heat to or between surfaces.
Copper's outer electrons are detached easily, making it great at causing an electron chain reaction. Copper is also used because of its price. While its price is increasing, its still far cheaper than other conductors.
A poor conductor of heat is any material that can not transfer heat. Poor conductors have a low density thus the particles in a given volume of the material are not enough to collide and transfer heat. Examples of poor heat conductors include air, wood, paper, cloth and water.
Metals conduct heat well for two reasons: metal ions pack very closely together in their molecular lattice, and electrons drifting through the metal carry kinetic energy around the lattice. The result is a quick elevation in particle motion that is expressed through heat energy. This conductivity is
Of the elemental metals, silver is the best conductor of heat. It has a thermal conductivity of 235, meaning that it is able to transmit that amount of heat energy a single foot per hour per degree Fahrenheit.
An orchestra conductor coordinates all the instrument members to think and perform collectively, according to the Los Angeles Times. Conductors do most of their work in training the musicians before a concert.
When salt dissolves in water, negative and positive ions are pulled in opposite ways by an electrical field, which creates an electrical current. The ions that are created include sodium, which has a positive change, and chloride, which has a negative charge.
