The metal in the wire combines with oxygen much faster because of the high heat which elevates energy state. As a result, the metal rapidly oxidizes and would actually weigh slightly more because each metal atom combines with an atom of Oxygen. This is why a light bulb metal wire filament burns out immediately if the glass bulb is cracked open allowing air to rush into the vacuum (also why it pops as it shatters). If this is the answer to your chem homework then I hope you learned something and weren't just being lazy.

Is Making silver jewelry a chemical change?
No, if your starting point is sliver wire or bar, the process making jewelry is mechanical, the raw material is heated and forged into jewelry, there is no chemical change.
Is sulfur combined with oxygen produces sulfur dioxide a physical change?
This is a chemical change because there is a molecular change in the composition. A physical change results when the size, shape, phase, texture etc. of a substance changes. Liquid water heated to water vapor is a physical change.
What happen if a flask is heated on a flame with a wire gauze?
- the flask is protected - the liquid is heated more uniform
What happens to the matter in copper wire when heated?
The matter in copper wire melts then explodes into a green flame
Is forming a bar of gold into wire a physical change or a chemical change?
Forming a bar of gold into wire is a physical change, not a chemical change. In this process, the gold undergoes a change in shape and physical state, but its chemical composition remains unchanged.
Is water heated and changed to steam a physical or chemical change or both?
physical only, you are only changing its state, not its composition.
What parameters do you change in volume control ventilation to increase expiratory time?
what is the purpose of a heated wire circuit
Does wire expand when heated?
yes wires do because when the wires are heated the particles inside the wires change speed and move faster. this causes them to bump into one another and expand!
Composition of copper wire in generators?
how much copper is in copper wire
What happens to the wire when heated?
it goes up
Is bending a metal wire a physical or chemical change?
It's a physical change, because bending a wire doesn't affect the chemical makeup of it.
What are the energy change when a wire gauze is heated wityh a bunsun burner?
Natural Gas, CH4, is rapidly oxidized producing heat, CO2 and water. The heat is absorbed by the wire gauze and surrounding atmosphere.
Is Making silver jewelry a chemical change?
No, if your starting point is sliver wire or bar, the process making jewelry is mechanical, the raw material is heated and forged into jewelry, there is no chemical change.
Does the composition of the ice change when it melts?
The composition of ice is H2O, and once it melts to water, its composition is ... H2O! So, no, the composition does not change.
When current passes why copper wire does not get heated while the bulb gets heated?
copper wire is good conductor of heat but bulb is bad conductor of heat.
Is sulfur combined with oxygen produces sulfur dioxide a physical change?
This is a chemical change because there is a molecular change in the composition. A physical change results when the size, shape, phase, texture etc. of a substance changes. Liquid water heated to water vapor is a physical change.
Does talc change color if heated?
Talc don't change the color if heated.
