The electrical resistance in a common piece of metal such as copper wire would increase.
This happens because as temperature increases the atoms of the metal vibrate quicker and to a larger extent resulting in a greater number of collisions for electrons moving along the metal.

What are cold resistance and hot resistance?
Metals heat up as electrical currents flow through them. Cold resistance is the metals resistance before it is operating. Hot resistance is the metals resistance after operating time has elapsed some.
What do you mean by 'cold resistance' and 'hot resistance'?
Metals that make up typical resistors (and many other electrical components for that matter) tend to heat up as current flows through them. "COLD" resistance is the resistance before it is operating and "HOT" resistance is the resistance after some operating time has elapsed.
Why does nichrome get hot?
Nichrome has a high electrical resistivity.
What is hot hardness?
Hardness is a characteristic that applies to a range of materials-metals and nonmetals alike- and is defined as the resistance of the material to deformation.
What is Hot Resistance?
Hot resistance is your total resistance you can have with out exceeding your wattage limit
What happens when two metals get mixed together?
When two metals are mixed together, they can form an alloy. Alloys combine the properties of both metals, such as strength, durability, and resistance to corrosion. The exact properties of the resulting alloy will depend on the metals used and their proportions.
Temperature coefficient of resistance?
most metals resistance increases with temperature
How does resistance of metal vary with temperature?
The resistance of metals generally increases with temperature due to increased atomic vibrations that impede the flow of electrons. This relationship is described by the temperature coefficient of resistance, which varies for different metals.
What is hot working of metals?
Hot working of metals is defined as a process of forming metals by deformation at temperature above the recrystallization temperature.
What is the lowest contact resistance of all metals?
The lowest contact resistance of all metals is typically observed in gold, due to its excellent conductivity and resistance to oxidation. Gold's atomic structure allows for optimal electron mobility, resulting in minimal contact resistance when in contact with other metals. Additionally, its corrosion resistance ensures stable electrical connections over time. Other highly conductive metals like silver and copper also have low contact resistance, but gold often remains the best choice for critical applications.
What is the definition of metals?
Ferrous metals are those contain iron. All ferrous metals are magnetic and give little resistance to corrosion.
What happens when non metals react with metals?
they form a salt
