Question

Which are properties of both a gas and a plasma? Check all that apply.

(1)can change shape to conform to a container
(2)has a rigid shape that does not change easily
(3)is made up of free-moving ions and electrons
(4)is compressed more easily than other states
(5)has particles that can wiggle but cannot move
(6)has particles that move freely from place to place
(7)will expand to completely fill a closed container

Answer 1

the correct answers are B &E.

Answer 2

The answer is 4, 6 and 7. Gas and plasma share most similar properties. The difference lies in the fact that plasma is composed of ions and electrons (ionized gas) as opposed to gas that is composed of neutral molecules. Therefore plasma can conduct electricity while gas cannot.
