Because the electrons in the atoms of the metal are being excited to a higher energy level they must "de-excite" and go back down to a lower level. When this occurs EM radiation is given off. If this radiation is in the visible light domain it will have an associated wavelength. This wavelength happens to be in the visible spectrum of red/orange/yellow light when metal is heated. Also, there are other types of non-visible radiation when heated, i.e. IR radiation.
What else can I help you with?
Things which change their state when heated?
Ice melts into water, wax melts into liquid, and metal expands when heated.
What will happen to the size of gold ring when heated?
When a gold ring is heated, it will expand in size due to the increase in temperature causing the molecules to move more vigorously, resulting in the metal structure expanding. As the ring cools back down, it will contract and return to its original size.
What is vermiculite made out of?
Vermiculite is a naturally occurring mineral that expands when heated. It is composed of a group of hydrated laminar minerals. When heated, it expands to create lightweight, fire-resistant, and absorbent material commonly used in gardening, insulation, and construction.
When a substance is heated what is it called?
Thermal Decomposition
When air is heated it becomes what?
When air is heated, it expands and becomes less dense. This causes its molecules to move more quickly, increasing the air's temperature.
Why do train tracks expand?
Metal expands when it is heated. Since track is made of metal then it expands when it is heated by the sun.
Will the volume of metal decrease if it is heated?
No, the volume of a metal increases as it is heated. It expands.
What kind of metal expands most when heated?
Lead...
When metal is heated and expands will the metal get larger or smaller?
When metal is heated, it expands and becomes larger in size. This is because heating the metal causes the atoms to vibrate more, which in turn increases the space between them, resulting in expansion.
Why did concord expand during flight?
Metal expands when heated, friction.
What happens when metal plate with circular hole is heated?
When a metal plate with a circular hole is heated, the metal expands due to the increase in temperature. As a result, the size of the hole also expands slightly. This phenomenon is known as thermal expansion.
What happens to the particles in a metal when the metal is heated?
When a metal bar is heated....the particles in the area of the metal bar that is hot start vibrating.. knocking into each other and passing the heat energy on to cooler particles. The cooler end that isn't heated still has a rise in temperature just not as much as the heated area because the heat has almost been diluted.
Things which change their state when heated?
Ice melts into water, wax melts into liquid, and metal expands when heated.
Why metal expands when heated?
Molecules move back and forth faster and faster causing expansion
What expands when heated?
Most substances expand when heated because the heat causes the particles to move more rapidly, increasing the space between them and causing them to take up more volume. This expansion is known as thermal expansion and is a common physical property exhibited by solids, liquids, and gases when exposed to heat.
What does matter do when it is heated?
Matter expands when it is heated.
What happens to the hole in a circular metal when it is heated and why does not the hole grows smaller if the sheet expands?
As the circular metal sheet is heated, it expands uniformly in all directions, including the hole. However, since the hole is not a separate entity but simply a void within the metal, it does not grow smaller or larger. The hole appears to change size relative to the expanding metal because of the way our eyes perceive the interaction between the sheet and the hole.
