The standard deviation of speed ($\sigma_c$) for Maxwell's distribution satisfies the relation

(a)$\sigma_c \propto T$

(b)$\sigma_c \propto \sqrt{T}$

(c)$\sigma_c \propto \frac{1}{T}$

Answer

Answer (as printed): B

Explanation

standard deviation of Maxwell’s speed = 𝑉O − 𝑉 O O − 𝑉O = 𝑟^5_ `ab cR- eR- e R- e R- = − = 3− = 3− d fd f d f d R- R- =0.67 = 0.7 , 𝜎Ð ∝ 𝑇 d d
