Question

Map do The graph at the right shows a Maxwell speed distribution for nitrogen molecules. Let Vrms = the "rms-speed, Vav.-the average speed, Vmp the most probable speed. 0.002 p note: ks 1.381 x103 JK take: m 4.65 x10-25 kg N, molecules T-29- K Answer the three questions below, using three significant digits. E 0.001 E Part A: Which of the following are true regarding Vms, Vave and Vmp? O Vmp has the greatest value O Vave has the greatest value O Vms has the greatest value O Actially, none of these are true. 400 80? 1200 v (m/s) Part B: Which value corresponds to the peak in the speed distribution? Vrms O None of these O Previous 0 Next Save And Ex

Explanation / Answer

(a) We know that Vrms has the greatest value as compared to the other.
Therefore the correct option is C.
(b) Corresponding to peak the speed is known as Most probable speed(Vmp). therefore the correct
option is A.
(C) We know that the
Vrms = (3kT/m)1/2
= [(3*1.381*10-23*4.5*102)/4.65*10-26]1/2
= 633.195 m/s
