Which device involves the use of plasma in technology? arc welder diesel engine incandescent lightbulb battery-operated flashlight
Answers
Ans : Arc welder
Plasma technology is based on the principle that matter changes its state when energy is supplied to it. When high energy is supplied to a gas, it gets ionized and goes to the fourth state of matter, plasma.
Plasma arc welding uses this principle and is similar to gas tungsten arc welding.
Plasma technology: The change of state of matter when energy is supplied to it makes the solids to becomes liquid and the liquids to becomes gas.
If more energy is supplied to gas, it gets ionized and enters into the energy-rich plasma state.
The plasma state is the fourth state of matter.
The principle of arc welder: A welding process where heat generated by an electrical arc is struck between an electrode and the element to be welded. The arcs are electrical discharges with light between the two electrodes as the gas is ionized.
As the gas is ionized, arc welder uses the principle of plasma technology.
Hence, arc welder is the answer.
