Why do atoms of certain elements give off light of characteristic color when heated to high temperature?
Atoms of certain elements give off light of characteristic color when heated to high temperature since the electrons induce to absorb energy, jumps to the excited energy state called quantum jump and then returns to their ground state. The amount of energy in the photon determines its color.

Does a compound melt when heated?
It depends on the specific compound. Some compounds will melt when heated to a certain temperature, while others may decompose, ignite, or undergo chemical reactions instead of melting. The melting point of a compound is a characteristic physical property that varies depending on the compound's chemical structure.
What information does a flame test provide?
The emission spectrum of an element
What were the elements Bunsen discover?
Robert Bunsen, a German chemist, is known for discovering the elements cesium and rubidium in 1860 by using spectroscopic analysis. These elements were identified using the characteristic spectral lines emitted by their atoms when heated in a Bunsen burner flame.
What color is silver in the flame test?
Silver does not produce a distinctive color in a flame test. It does not exhibit a characteristic flame color like other elements when heated in a flame.
Are elements in a compound heated until they boil?
No, elements in a compound are not necessarily heated until they boil. Boiling point is the temperature at which a substance changes from a liquid to a gas. Heating a compound can be used to separate its components by taking advantage of differences in boiling points through techniques such as distillation or chromatography.
What is the purpose of flametest?
Flame test is used to identify the presence of certain elements in a sample based on the characteristic color produced when the elements are heated in a flame. It is commonly used in chemistry to detect the presence of metal ions in compounds.
What is pasterization?
pasterization is where food is heated to a certain temperature to keep it fresh.
Does a compound melt when heated?

What is mean by preheat temperature in welding?
Some materials have to be heated before you start to weld on them. They will probably have a maximum interpass temperature, and may also need to be kept heated to a specific temperature for a certain amount of time after you stop welding (called post heat).
What were the elements Bunsen discover?
Robert Bunsen, a German chemist, is known for discovering the elements cesium and rubidium in 1860 by using spectroscopic analysis. These elements were identified using the characteristic spectral lines emitted by their atoms when heated in a Bunsen burner flame.
What do enzyme amylase do?
Well if mixed with starch it breaks down the starch to form the sugar maltose when heated at a certain temperature.
How does go into the air?
If water is heated to a certain temperature, it evaporates. When water evaporates, it...I guess you could say..."go into the air".
Who observed that if an object is heated to a high temperature it emits radiation in a certain way?
Max Planck observed that if an object is heated to a high temperature, it emits radiation in a way that is related to its temperature. This observation led to the development of quantum theory and Planck's formulation of the quantization of energy levels in a system.
How does water go into the air?
If water is heated to a certain temperature, it evaporates. When water evaporates, it...I guess you could say..."go into the air".
What elements exist in liquid form?
Elements such as mercury and bromine exist in liquid form at room temperature. Mercury is a transition metal that is liquid at room temperature, while bromine is a nonmetal that is also liquid at room temperature.
What color is silver in the flame test?
Silver does not produce a distinctive color in a flame test. It does not exhibit a characteristic flame color like other elements when heated in a flame.
