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.
When alum is heated they liquify and as the waterÊcrystalines evaporate turningÊthe alumsÊin to an amorhous powder. Alums are astringent and acidic. Alums are also used in the preservations of drinking water.
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.
A heated liquid become a gas at the boiling point.
Neon
Evaporation is the process and the gas formed by liquid in heated condition is called vapours
Heating will cause the gas to expand; or, if the container does not permit expansion, for the pressure of the gas to increase. Other changes to the gas depend on which gas is being heated.

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.
The chemical formula of calcium carbonate is CaCO3. It emits CO2 when heated. This gas tuns lime water into milky white when reacted.
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.
The gas will expand as it is heated.
Neon emits a red to orange colour
A large celestial body that is composed of gas and emits light is called a star.

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.
