The velocity, V of a gas is related to its mass, M by (k = proportionality constant)
-
A.
V = (frac{k}{M}) -
B.
V = (frac{k}{M^{frac{1}{2}}}) -
C.
V = (kM^2) -
D.
V = ((frac{k}{M})^{frac{1}{2}})
Correct Answer: Option B
Explanation
Recall:
V = (sqrt{frac{3RT}{M}})
(therefore V propto frac{1}{sqrt{M}})
(V = frac{k}{sqrt{M}})
V = (frac{k}{M^{frac{1}{2}}})
