Problem
Three curves A, B, and C represent Maxwell–Boltzmann speed distributions for the same monatomic gas at three different temperatures.
• Curve A peaks at speed vp and is of moderate width.
• Curve B peaks at a speed lower than vp and is noticeably narrower than Curve A.
• Curve C peaks at a speed higher than vp and is noticeably broader than Curve A.
Which of the following gives the correct ranking of the gas temperatures from lowest to highest?
(a) TA<TB<TC
(b) TB<TC<TA
(c) TB<TA<TC
(d) TC<TA<TB
