Because the molecules in metal are slower when cold and therefore let electricity run through it easier.

Why can't electricity flow through coin?
It can.Electricity, both static and current, flows through coins quite easily.
What material allows electricity to pass through it easily?
Metals. Copper has one of the lowest resistivities. Resistivity is a measure of how easily electricity flows - the lower the better the electricity flows. Silver has an even lower resistivity but obviously it is more expensive. Aluminium is also good but it oxidises so would not be as good a conductor as copper which resists oxidation.
Heat flows easily on what material?
Heat moves easily through materials with delocalised electrons, that is electrons which are free to move through the substance. This happens in metals and graphite.
A property that shows how easily heat or electricity flows through matter?
Conductivity - either thermal conductivity, or electrical conductivity.
What is the path which electricity travels called?
The path of electricity is called a circuit.
How come the metals are a good conductor of electricity?
metals have electrons in the valence band that easily separate, forming an "electron gas" that fills the metal. This "gas" readily flows in response to an electric field placed across the metal.
What lights up when electricity flows through?
Electricity flows through the path of least resistance. Electricity will flow through anything conductive; metals, liquids, and even through small particles. Your insulators are porcelain, glass, plastics, wood and cloths. All variances of voltage is deadly. The most dangerous thingabout electricity is the current or amperage. As little as 17 miliamps can stop your heart.
How do you make electricity out of a lemon?
electricity flows through the wire into the lemon
The measure of how easily electricity flows through a material is called?
The conductance. The reciprocal (how HARD it is for electricity to flow) is called the resistance. This is used more commonly than the conductance.
Why metals are good conductors?
Metals are good conductors of both electric charges and heat because their electrons are "loose." (info from physics book)
What complete path through electricity flows?
A circuit.
What kind of electricity that flows through the electric flat iron?
Alternating current flows through a flat iron.
