Plasma refers to a hot ionized gas possessing high electrical conductivity. It is electrically neutral with negative and positive particles. It can be considered the most abundant form of matter in the universe.  

The features of plasma are substantially distinct from those of the usual neutral gases so that plasmas are regarded as a different fourth state of matter.

During which phase change does the entropy of a sample of H2O increase?
Bezzdna [24]

Answer: 3. H2O(l) -> H2O(g)

Explanation: Entropy is a measure of the randomness or disorder a substance. Gasses have the greatest amount of entropy and solids have the least amount of entropy. The entropy of a sample of H2O increases as liquid water evaporates and changes to a gas.
