Which of the following do you think use plasma? welding rocket engines computer chips surgery chemical analysis ozone generation

Answer;

Rocket engines

Explanation;Plasma is a hot, dense ionized state similar to that inside a fusion reactor or star.Some type of rocket engine uses electrical source to transform hydrogen gas into plasma.Then powerful magnets force the plasma out of the engine to propel the rocket at very high speeds of about 123,000 mph.Instead of fuel, plasma jet engines use electricity to generate electromagnetic fields. These compress and excite a gas, such as air or argon or hydrogen, into a plasma.
