Question

Match each quantity in Column I with the statements in Column II that are true for it (a Column I entry may match more than one Column II entry):

Column I (Quantity)	Column II (Statement)
(P) most probable speed	(1) proportional to $T / M$
(Q) average speed	(2) independent of the molar mass at a given T
(R) root mean square speed	(3) proportional to T
(S) average kinetic energy per molecule	(4) the greatest of the three speeds
	(5) the smallest of the three speeds

Choose the option with the correct matching:

TestHub · Accepted Answer

u m p ​ = 2 RT / M ​ (smallest), u a vg ​ = 8 RT / π M ​ (in between), u r m s ​ = 3 RT / M ​ (greatest). (P) 1, 5. (Q) 1. (R) 1, 4. (S) Average KE = (3/2)kT is proportional to T and does not depend on M: 2, 3. Correct matching: P to 1,5; Q to 1; R to 1,4; S to 2,3. Answer: (D).
