    For the first question, you can cross out A, and most likely C. I'd have to say it's option B, molecules in a gas are shapeless. As for your second question, weight can change, but boiling point and density can be unique to a substance, helping you determine the identity of it. So your answer is A, boiling point, and D, density.
