Equal masses of gaseous N2 and Ar are placed in separate flasks of equal volume at the same temperature. Tell whether each of the following statements is true or false.
Briefly explain your answer in each case.
(a) There are more molecules of N2 present than atoms of Ar.
(b) The pressure is greater in the Ar flask.
(c) The Ar atoms have a greater average speed than the N molecules.
(d) The N2 molecules collide more frequently with the walls of the flask than do the Ar atoms.
