Plasma Ball And Fluorescent Lamp Experiment

What is Plasma?Plasma is considered the fourth state of matter. The three other states are solid, liquid, and gas. Plasmais actually the most common form ofmatterin the universe!Plasma is a cloud of protons, neutrons and electrons where all the electrons have come loose from their respective molecules and atoms, giving the plasma the ability to act as a whole rather than as a bunch of atoms. A plasma is more like a gas than any of the other states of matter because the atoms are not in constant contact with each other, but it behaves differently from a gas. It has what scientists call collective behavior. This means that the plasma can flow like a liquid or it can contain areas that are like clumps of atoms sticking together.
What is a Plasma Ball?
It is also called a Plasma Globe or a Plasma Lamp.It is a clear glass sphere filled with a mixture of variousnoble gaseswith ahigh-voltageelectrodein the center of the sphere.Plasma filamentsextend from the inner electrode to the outer glass insulator, giving the appearance of multiple constant beams of colored light.The plasma lamp was invented byNikola Teslaafter his experimentation with high-frequencycurrentsin an evacuated glasstubefor the purpose of studyinghigh voltagephenomena. Thats why the electrodeat the center of aplasmaball is also often known as a Teslacoil. Tesla called this invention aninert gasdischarge tube. The modernplasmaballs popular aseducational items today were designed byBill Parker. Typically, such lamps use anoble gasor a mixture of these gases and additional materials such as metalhalides,sodium,mercury or sulphur.The most common noble gas used is Neon. Neon is a chemical element with symbol Ne and atomic number 10.
Plasma filamentsThe electricity from the electric diode creates plasma filaments which appear like blue and purple light.
What Happens When We Touch It?
Placing a hand near the glass offers an attractive place for the energy to flow.Touching it causes a single filament, from the inner ball to the point of contact, to become brighter and thinner.The filament is brighter because there is more current flowing through it.
Fluorescent Lamp Afluorescent lampor afluorescent tubeis a low pressuremercury-vaporgas-discharge lampthat usesfluorescenceto produce visible light. Anelectric currentin the gasexcitesmercuryvapor which produces short-wave ultravioletlight that then causes aphosphorcoating on the inside of the bulb to glow. A fluorescent lamp converts electrical energy into useful light much more efficiently thanincandescent lamps. The typicalluminous efficacy of fluorescent lighting systems is 50100 lumens per watt, several times the efficacy of incandescent bulbs with comparable light output.Acompact fluorescent lamp(CFL) is a fluorescent lamp which uses a tube which is curved or folded to fit into the space of an incandescent bulb, and a compactelectronic ballastin the base of the lamp.
Plasma Ball And Fluorescent Lamp ExperimentWhen regular fluorescentlight bulbs are brought close to a plasma ball through which electricity is being passed through, they begin to glow. The bulbs glow because the electricity in the plasma globe is sent from the center of the ball at high frequencies, similar to radio waves. The noble gas inside the fluorescent bulbs react with the high frequency electricity and they begin to glow!
