What is the effect by which an object begins to glow while heated?
When an object begins to glow while heated, it is due to incandescence, which is the emission of electromagnetic radiation (often in the form of visible light) as a result of being heated to high temperatures. As the object's temperature increases, the atoms or molecules within the object gain energy, causing them to emit light as they return to a lower-energy state.
What is the emission spectrum of elements list?
The emission spectrum of elements is a unique pattern of colored lines produced when an element is heated or excited. Each element has its own distinct emission spectrum, which can be used to identify the element.
Does a incandescent light bulb emit electrons by thermionic emission?
No, incandescent light bulbs do not emit electrons by thermionic emission. Instead, they produce light by heating a filament to such a high temperature that it emits visible light due to incandescence. Thermionic emission typically refers to the emission of electrons from a heated cathode in vacuum tubes or electron guns.
What is thermionic thermometer?
A thermionic thermometer uses the thermionic emission of electrons from a heated filament to measure temperature. When the temperature increases, the emission of electrons also increases, allowing for a correlation between temperature and electron emission. These thermometers are used in high-temperature applications and can provide fast response times.
What happens to the resistance of a common ohmic resistor when it is heated?
When a common ohmic resistor is heated, its resistance typically increases.
What happens to magnets when they are heated?
it will lose its magnetism OR it will get weaker
9 What happens to enzymes if you heat them up?
enzymes undergo denaturation when heated to high temperatures
What happens to copper carbonate and sodium carbonate when heated?
They both release carbon dioxide,but at different temperatures
What Happens To Motor Oil At Different Temperatures?
when motor oil is heated it viscotity rises and becomes thicker
What is a heated catalyst on your 1996 ford Taurus read at a emission diagnostic system?
That is a heated O2 sensor.
What is the name of the range of colors emitted by a heated atom?
The name of the range of colors emitted by a heated (energized, excited, etc...) atom is called an emission spectrum.
Different methods of separating electrons from atom using heat?
One method is thermionic emission, where electrons are released from a heated metal surface. Another method is field emission, where a strong electric field is used to pull electrons from the surface of a material. Additionally, heating a material to high temperatures can cause electron excitations that lead to electron emission.

What happens to silver when heated?
When silver is heated, it will expand due to the increase in temperature. At high temperatures, silver will oxidize and form a black layer of silver oxide on its surface. If heated further, silver will eventually melt at a temperature of 961.78 degrees Celsius (1763.2 degrees Fahrenheit).
What happens to matter when heated?
When matter is heated it will expand
What is the emission spectrum of elements list?
The emission spectrum of elements is a unique pattern of colored lines produced when an element is heated or excited. Each element has its own distinct emission spectrum, which can be used to identify the element.
What happens to most materials as they are heated?
Most materials expand when heated due to increased molecular motion, causing the particles to move farther apart. However, if heated to extremely high temperatures, materials can undergo phase changes, such as melting or vaporization. Additionally, some materials may decompose or undergo chemical reactions when heated.
