3) Gas or air can be turned into plasma when artificially ionized.
Choose the correct statements from the codes below.

3 only. 1, 3 only. 2, 3 only. 1 only.

9. Sun spots are the one found on the outer surface of the Sun.
Consider the statements regarding Sun spots.
1) Sun spots region generally have lower temperature than the surrounding region on the Sun’s outer surface.
