True or false, FLUORESCENT light is produced by heat.?

false. you're runing a current through the gas which causes it to fluoresce.True or false, FLUORESCENT light is produced by heat.?
falseTrue or false, FLUORESCENT light is produced by heat.?
False!
false
False





a current is passed thru a gas(often inert) and the particles are 'excited' by the charge and vibrate when they collide they fluoresce
False. Fluorescence occurs because something, often light, provides energy to the electrons within a material. These electrons retain that energy, which causes them to be promoted to a higher energy level. After some time passes the electrons will lose this energy, and because of energy conservation a photon is emitted. It is this photon which is the fluorescent light. Phosphorescence works in the same way only using different decay pathways to lose the energy.
false. it's caused by gas and chemical reaction.
false
false, it is caused by chemical reactions, which can then produce heat
