Because the molecules in metal are slower when cold and therefore let electricity run through it easier.
The electrical and thermal conductivity of metals originate from the fact that in the metallic bond, the outer electrons of the metal atoms form a gas of nearly free electrons, moving as an electron gas in a background of positive charge formed by the ion cores. Good mathematical predictions for electrical conductivity, as well as the electrons' contribution to the heat capacity and heat conductivity of metals can be calculated from the free electron model, which does not need to take the detailed structure of the ion lattice into account.
The free electron model is a simple model for the behavior of valence electrons in a crystal structure of a metallic solid, in which valence electrons are assumed to be completely detached from their ions (forming an electron gas). As in an ideal gas, electron-electron interactions are completely neglected (they are weak because of the shielding effect). This allows for excellent electric conductivity since a current is caused by the movement of electrons freely through a medium, and the free cloud of electrons in the nucleus lattice allows for that to freely occur.
Simply put, the nature of atoms within a metal object is hypothesized to be a rigid crystal lattice of nuclei, surrounded by a cloud of free electrons. This allows a current (a flow of electrons) to be passed through with relative ease. The hypothesis is valid since detailed experiments and calculations appear to confirm this. Also because I am awesome! Hee Hee Hee!
Electricity flows easily through metals because of their free electrons that can move freely through the material. When a voltage is applied, these free electrons are able to carry the electric current through the metal, allowing for efficient conduction of electricity. Metals are good conductors of electricity due to their atomic structure and the presence of these free electrons.
Metal has chemical properties where the electrons of the atoms in the metal flow like a river so that the current stimulates the electrons so that the flow, which is the current passing through the metal.

Why does electricity not flow in wood?
Electricity does not flow well through wood because wood is a poor conductor of electricity. The electrons in wood are tightly bound to the atoms, making it difficult for them to move freely and carry an electrical current. As a result, wood does not allow electricity to flow through it easily.
Why is iron a good conductor of electricity?
Iron is a good conductor of electricity because it has a high number of free electrons that are able to move freely throughout its atomic structure. This allows electricity to flow easily through iron, making it an efficient conductor.
Does electricity pass through a metal coin?
Yes, electricity can pass through a metal coin if it is conductive. Metals such as copper, silver, and gold are good conductors of electricity, so if a coin is made of one of these metals, then electricity can flow through it.
Is a nail an insulator or conductor?
both. most are conductors but some now made today are insulators which are mostly used in carpentry. but common nails are conductors.give me trust point? (:Conductor as they are made from metal.
Will electricity flow through a plastic comb?
No, electricity will not flow through a plastic comb because plastic is an insulator and does not conduct electricity.
Why is it dangerous to stick a metal knife into an electric outlet?
Metal is a conductor and the electricity will easily flow through it.
Can electricity flow through metal?
Yes, electricity can flow through metal.
What is a conductor of electricity and an insulator of electricity?
A conductor of electricity is a material that allows electric current to flow through it easily, such as metals. An insulator of electricity is a material that does not allow electric current to flow through it easily, such as rubber or plastic.
Where in the periodic table does heat and electricity does not flow easily?
non-metal.
Is metal a conductor of electricity or an insulator?
Metal is a good conductor of electricity. It has free electrons that can move easily through the material, allowing electricity to flow through it.
Is a dime an insulator or conductor?
A dime is a conductor of electricity because it is made of metal. Metal objects like dimes allow electric current to flow through them easily.
Why is it possible for electricity to travel through metal?
Metal is a conductor. What this means is that it has a very low resistance to electricity, allowing the electricity to flow through it. I suggest you learn how electricity works first to understand how electricity can flow through objects. http://millerwelds.com/education/basicelec/
Is metal coat hanger a conductor or insulator?
A metal coat hanger is a conductor of electricity because it is made of metal, which allows electric current to flow through it easily. Insulators, on the other hand, do not allow electric current to flow through them easily.
Can electricity flow through iron gold?
I don't know what "iron gold" is, but electricity will flow through any metal pretty well.
Is a hair clip a conductor or insulator?
insulator
