Pretty much all wires are made from materials with a positive coefficient of thermal expansion - which means that as they cool, they contract (get shorter).

What factors effect the resistance of a wire?
Its elemental makeup. Its' diameter and its' length.
What will be the effect on specific resistance if length of wire is halved?
it will not effect it because it only depends upon property of medium
What is effect of voltage and current by changing the length of wire?
By changing the length of wire, say reducing it, the resistance will drop and that will increase current flow but the voltage is less likely to change V=IR.
What is the Effect of length of pipe in split ac on cooling effect?
There is little effect, other than the need for more refrigerant (freon) to fill the lines. You can put them as far away as you like.
What is the Change in resistance of wire when its length is double?
Assuming the wire follows Ohm's Law, the resistance of a wire is directly proportional to its length therefore doubling the length will double the resistance of the wire. However when the length of the wire is doubled, its cross-sectional area is halved. ( I'm assuming the volume of the wire remains constant and of course that the wire is a cylinder.) As resistance is inversely proportional to the cross-sectional area, halving the area leads to doubling the resistance. The combined effect of doubling the length and halving the cross-sectional area is that the original resistance of the wire has been quadrupled.
Does ozone layer has cooling effect?
Ozone does have a cooling effect. It is because of its properties.
Is one of these be important in the formation of clouds the cooling of air as it rises the Coriolis effect the relative length of day and night or the melting of the polar ice caps?
The cooling of air as it rises is important for forming clouds.
What is the formula to calculate length of the wire?
There is no formula to calculate the length of a wire. The length of a wire is determined by the distance from the power source to where the load is situated.
How does the resistance of a wire vary with its length?
resistance of wire increases with increases of length
Science fair do heating and cooling effect the strength of glass?
No, heating and cooling does not effect the strength of a glass
What happens to voltage when wire length increase?
When the length of the wire increases voltage drop across the wire will occur.There are two factors that can result in voltage drop. One diameter of the wire, two length of the wire.Voltage drop increases with increase in length of wire, whereas voltage drop decreases with increase in diameter (cross section area) of the wire.G.RAOAnswerIf you are asking what happens to the voltage across a length of wire when its length increases, the answer is nothinghappens! The voltage applied to the wire is determined by the supply, not by the load (i.e. the wire).
Are there cooling mats for my PlayStation 3?
No, but laptop cooling mats (or cooling pads) can be used to the same effect.
