Question

Gas can be turned into a plasma on earth with the addition of:

• A. great amounts of energy
• B. great amounts of liquid
• C. another gas
• D. water
• E. great amounts of time

Answer 1

Answer: (A)

great amounts of energy

Plasma is called fourth state of matter. In this state every substance remains in gaseous state, this gas has only ions and free electrons. This state is obtained by freeing all the electrons from the attraction of nucleus. To make the electrons free from nucleus we have to give them energy equal to or greater than the energy by which they are bound with nucleus, therefore for that we require a great amount of energy.
