Plasma globes or plasma lamps are filled with noble gases and a high voltage electrode. The most common gasses are neon, argon, xenon, and krypton.
It was David Krypton lamp.
krypton-86 lamp
Yes, lava lamps contain small amounts of krypton gas as a component of the overall mixture. Krypton is used to control the buoyancy of the wax blobs inside the lamp, helping them rise and fall in a mesmerizing manner.
Yes, it is a chemical change.
Kr on the periodic table stands for krypton. Krypton is a colorless, odorless noble gas element that is commonly used in lighting, such as in fluorescent lamps and plasma screens.
A plasma arc of argon gas and/or other ions, such as mercury vapour, depending on the gas mixture used in the lamp.
If the sleeve on the lamp is quartz, it could / might make ozone. If the sleeve is a more common glass, it will make little or no ozone. A hint as to what this clear stuff is, might be if they provided precautions for handling it and cleaning it.
You might be thinking of a Plasma Lamp.
The type of gas commonly used in an arc lamp is typically a noble gas such as xenon or mercury vapor. These gases are chosen for their ability to produce a bright and steady light when an electric current is passed through them in the lamp.
Krypton is used to fill electric lamp bulbs which are filled with a mixture of krypton and argon, and for various electronic devices. Krypton is also used in photographic projection lamps, in very high-powered electric arc lights used at airports and in some strobo-lamps, because it has an extremely fast respons to an electric current.
Krypton Tetrafluoride
It's a fraction of normal atmospheric pressure, but each type of lamp has a particular pressure, depending on the type of gas and the application.
