Which metal is the best conductor of electricity and why?
The most common one that is very effective is METAL. Well, metal is not an element Of elements, silver is the best conductor of heat followed by copper. The best conductor of heat overall at room temperature is diamond, not an element of course.
What causes water to conduct electricity.?
Water ionises to a small extent to produce hydrogen ions an hydroxide ions according to the following reversible reaction: H20 <-> H+ + OH- Although, the reaction tends to lean towards the reverse reaction. It is still able to produce sufficient quantity of hydrogen ions and hydroxide ions needed to conduct electricity. Water conducts electricity through the migration of hydrogen and hydroxide ions.
Why is aluminum a element?
firstly......aluminum is a metal by itself in nature.... aluminum is considered as a metal for the following reasons: 1 - aluminum is a solid at room temperature and has a relatively high density 2- aluminum can be hammered into sheets and drawn into wires most importantly, 3 - aluminum is a very good conductor of heat as well as electricity All the above properties belong to metals; hence aluminum is considered as a metal.
How do you identify if a substance is metal matalloid or non metal?
In simple terms just by looking at them, and doing an electrical conductivity test you can tell the following. the metals are shiny and conduct electricity. The non-metals which are gases or liquids are easy to distinguish. The solid non metals such as sulfur are not shiny and do not conduct electricity. (graphite conducts electricity but is soft and not that shiny). The metalloids look a bit like metals but are very poor conductors of electricity.

Is silicon a good electricity conductor?
This depends on a few parameters of which the purity and the temperature have a significant influence. For pure silicon (typically less than ppba levels of impurites (parts per billion atom), the conductivity can be represented by the following equation: log (specific conductivity) = 4.247 - (2924/T) where T is the temperature measure in Kelvin units. From a practical sense, silicon behaves like an insulator at less than 700 deg K and as a conductor at much higher temperatures.

What will be Heat developed in current carrying carrying conductor?
Any conductor has resistance. Maybe not much, but there's always some.Any resistance dissipates power, at the rate of I2R. (I = current through it, R = its resistance.)That's how you build toasters.
