Solution: Consider the following drawing.If curves A and B refer to two different gases, He and O2 at the same temperature, which curve corresponds to He?

Problem

Consider the following drawing.

A graph shows fraction of molecules versus molecular speed for gases A and B. Gas A peaks higher and to the left of gas B. The x axis is molecular speed and the y axis is fraction of molecules (both axes are unscaled). Gas A rises to a peak about two-thirds of the way up the y axis with the peak at about one quarter the length of the x axis. Gas B rises to a broad, lower peak about one third of the way up the y axis and about halfway across the x axis.

If curves A and B refer to two different gases, He and O2 at the same temperature, which curve corresponds to He?
