Three statements are made below. Pick the correct answer.
I. The molecular speed of N₂ gas is greater than SO₂ gas if both are at the same temperature.
II. For an ideal gas we assume there are no attractive forces between molecules.
III. For gases and liquids, the molecules are in constant motion.

Question
