How does gas turn into a plasma?

Answer 1

A gas can change state to become a plasma if it is given enough energy. Adding electrical energy or thermal energy will drive electrons off the gas atoms and ionize them. The ionized gas atoms are now a plasma. This change of state is a physical change, and not a chemical one. Lastly a plasma can be created at different temperatures, and this will depend on the gas atoms being heated to become a plasma.

Answer 2

If we add energy to a gas, we can strip electrons off the gas atoms. This creates a plasma. Sufficient electrical voltage or a lot of heat (thermal energy) can do this. A plasma arc created by a gap across which we apply a voltage is one example. And if we consider something like the body of the sun, we find it is a superheated mix of atomic nuclei, which is a plasma.

Answer 3

When a gas is heated to extremely high temperatures, the electrons gain enough energy to break free from their atoms. This causes the gas to ionize, forming a plasma where the ions and free electrons coexist. In a plasma state, the gas is electrically conductive and exhibits unique properties different from those of a gas.
