(B) Average speed of gas molecules
(C) Molecular weight of gas molecules
(D) Volume of gas sample
(E) VolatilityYou know that increased heat increases average kinetic energy, but the answer
has been camouflaged.
Maybe you’re not used to thinking of the “addition of thermal energy” resulting
in an increase in temperature. When it comes to gases, you’re also not
accustomed to thinking of “average speed of gas molecules” as reflecting the
average kinetic energy. Although you know your chemistry, you might not
realize that the right answer to this question is B. You might decide to pick some
crazy answer such as A or D. Why? Because you fell into the trap.
