There is no such thing as a "gaseous liquid". There is a state of matter called a GAS and a state of matter called a LIQUID and matter can move between these states.
Further, Television tubes contain a vacuum.
Yes, all of them.
The change in state would be known as melting. Just for your information: Solid to Liquid = Melting Liquid to Gaseous = Boiling Solid to Gaseous = Sublimation Gaseous to Liquid = Condensation Liquid to Solid = Freezing Gaseous to Solid = Deposition
Some early flat screen TVs used cathode ray tubes, but the flat faced tubes were harder to make and heaver than the older curved faced tubes. When newer designs (e.g. plasma, LCD, LED) came out that naturally produced flat screens and were lighter weight than cathode ray tubes, they rapidly made flat screen cathode ray tube TVs obsolete.
From solid to liquid, from liquid to gaseous, from gaseous to liquid, from liquid to solid, and in sublimation from solid to gaseous or the reverse, chemical properties do not change.
it is a rare gaseous element found in the atmosphere, it is obtained by liquifying air and separating it from other elements. Neon advertising signs account for the bulk of its use as well as TV tubes. It was discovered in 1898
solid = ice liquid = water gaseous = water vapour
No. Liquid oxygen and gaseous oxygen are the same substance, just in different states.
Water condenses from a gaseous to a liquid form at 100 degrees Celsius.
Sublimation
Neon is a member of the noble gas family. Neon is used to make neon signs and television tubes. Liquid neon is used as a cryogenic refrigerant.
Gaseous water is called steam.
Yes, when a liquid turns into a gaseous state, it is known as vapor. This process is called vaporization or evaporation.
