Which sample of gas is least likely to behave ideally? A) 1 mol He(g) at 400 K, 1 atm pressure B) 1 mol Ne(g) at 400 K, 1 atm pressure C) 1 mol H₂(g) at 400 K, 1 atm pressure D) 1 mol O₂(g) at 400 K, 1 atm pressure E) 1 mol H₂O(g) at 400 K, 1 atm pressure

Question

Quizplus · Accepted Answer

Water vapor (H₂O) is polar and can form hydrogen bonds, which makes it deviate from ideal gas behavior more than nonpolar gases like He, Ne, H₂, and O₂.
