A content analysis of students' responses to a particulate multiple-choice gas question identified three possible threats to the validity of this question. This presentation will describe research performed to test whether providing students with the boiling point of the gas and whether instruction focusing on rigid and non-rigid containers will affect students' abilities to answer conceptual questions related to this famous multiple-choice gas question.
