Which of the following best describes plasma?
A) a group of super cooled particles with very low kinetic energy
B) an ionized group of particles with low kinetic energy
C) a gas that becomes a solid without first becoming a liquid
D)an electrically charged gas with very high kinetic energy
D) is best, but they should have said temperature instead of kinetic energy. Kinetic energy is often associated with the flow velocity of the gas, which can be zero. The average kinetic energy of the atoms, electrons and ions is associated with the temperature.
