Particles in the solid state (a) from a regular repeating pattern and are constantly vibrating in the liquid state (b) move more freely in the gaseous state (c) move rapidly and freely, and in the plasma state (d) move rapidly but their be controlled by a magnetic field due to the interaction between the charged particle and the magnetic fields.
What is ionization?
When gas particles are in extremely high temperature above 1000,000 C, they become charged particles or ions. Another way, when a particle is collided a negative or positive charge by gaining or losing electrons. The process is called ionization. Like gas, plasma does not have a definite shape or a volume unless enclosed in a container.
What is the shape of the plasma?
Plasma conducts electric current,but gases do not. Electric and magnetic field affect plasma , but do not affect gases.
A strong magnetic field is used to contain extremely hot plasma that would destroy a solid container.
