The answer is that it is dependent on the source. A sample of pure aluminum should not release any gas, aside from a small amount of oxygen due to a layer of aluminum oxide. As the source changes, so does the gas evolved. Carbonates will give carbon dioxide, sulphates: sulphur dioxide, etc.
What else can I help you with?
How are fumaroles different from hot springs?
A fumarole is a vent on or near a volcano that emits gas. A hot spring is a pool of water heated by an underground source.
What does heated liquid and gas become?
A heated liquid become a gas at the boiling point.
When gas is heated it emits light. explain why this phenomenon occurs?
When gas is heated, the energy causes the electrons in the gas atoms to become excited and jump to higher energy levels. As these electrons return to their original, lower energy states, they release the excess energy in the form of light. This emission occurs at specific wavelengths, resulting in the characteristic colors associated with different gases. This phenomenon is the basis for applications like neon signs and gas discharge lamps.
What is formed when water is heated and turns to a gas?
When water is heated and turns into a gas, it forms water vapor.
What gas is the most or least dense when heated?
When heated, gases typically expand and become less dense. So, a gas would be least dense when heated.
Does potash Alum Show sublimation or not?
Potash alum does not exhibit sublimation. Sublimation is the process where a substance transitions directly from a solid to a gas without passing through a liquid state. Potash alum undergoes decomposition when heated instead of sublimating.
Is alum sublime?
Oh, dude, like, totally! Alum is sublime, but not in a "wow, that's amazing" kind of way. It actually sublimes, which means it goes from a solid to a gas without melting first. So, yeah, alum is totally sublime in a chemistry kind of way.
How are fumaroles different from hot springs?
A fumarole is a vent on or near a volcano that emits gas. A hot spring is a pool of water heated by an underground source.
What chemical causes the baking powder to rise?
The ingredient in baking soda that causes baked goods to rise in the oven is sodium bicarbonate and alum or cream of tartar. Both alum and cream of tartar are acidic. Cream of tartar is used for alum free powders. Sodium bicarbonate is slightly basic. The reaction between the two chemicals when moistened and heated produces carbon dioxide gas which causes the cake to rise as the bubbles of CO2 gas get trapped in the cake.
Difference between direct and indirect cathode ray?
In a directly heated cathode, the filament is the cathode and emits the electrons. In an indirectly heated cathode, the filament or heater heats a separate metal cathode electrode which emits the electrons.
As a heated liquid turns into a gas it?

What is large celestial body that is composed of gas and emits light?
A large celestial body that is composed of gas and emits light is called a star.
What other uses are there for alum?
Alums are useful for a range of industrial processes. They are soluble in water; have an astringent, acid, and sweetish taste; react acid to litmus; and crystallize in regular octahedral. When heated they liquefy; and if the heating is continued, the water of crystallization is driven off, the salt froths and swells, and at last an amorphous powder remains. Potassium alum is the common alum of commerce, although soda alum, ferric alum, and ammonium alum are manufactured. Aluminum sulfate is sometimes called alum in informal contexts, but this usage is not regarded as technically correct.
What type of electrode is a cold cathode?
Cold cathode is a cathode, an electrode that emits electrons, which is not electrically heated by an element. Cold cathodes are used in gas discharge lamps such as neon lamps and discharge tubes.
Coke oven gas emits a high concentration of which gas?
Hydrogen gas 55%
What do you call a liquid that has been heated to a gas?
A liquid that has been heated to a gas is called vapor.
Why heated gas become lighter?
because..................................................................................................................... density of heated gas is lower than cooled gas.
