JEE PYQ: States Of Matter Question 12
Question 12 - 2020 (07 Jan Shift 2)
Identify the correct labels of A, B and C in the Maxwell-Boltzmann distribution graph.
$V_{\text{rms}}$: Root mean square speed; $V_{\text{mp}}$: most probable speed; $V_{\text{av}}$: average speed
(1) A - $V_{\text{mp}}$; B - $V_{\text{rms}}$; C - $V_{\text{av}}$
(2) A - $V_{\text{av}}$; B - $V_{\text{rms}}$; C - $V_{\text{mp}}$
(3) A - $V_{\text{rms}}$; B - $V_{\text{mp}}$; C - $V_{\text{av}}$
(4) A - $V_{\text{mp}}$; B - $V_{\text{av}}$; C - $V_{\text{rms}}$
Show Answer
Answer: (4) A - $V_{\text{mp}}$; B - $V_{\text{av}}$; C - $V_{\text{rms}}$
Solution
The order is $V_{\text{rms}} > V_{\text{av}} > V_{\text{mp}}$. From graph, A is the peak (most probable), B is next (average), C is furthest right (rms).
