Which of the following statements is not true?
Options:
Answer:
B
Solution:
(a) True: uav/urms = √(8/3π), a constant. (b) False: (uav)2 = 8RT/π M ≈ 2.55 RT/M, whereas the mean square speed overlineu2 = 3RT/M; they are never equal for a Maxwellian gas. (c) True: mean KE = 3/2kT depends only on T. (d) True: urms - uav = (√(3) - √(8/π))√(RT/M), which falls as M grows. The untrue statement is (b). Confirms Ans (b).
