PhysicsMediummultiple choice

A mixture of the ideal diatomic gases x \& y is enclosed in a container at constant temperature. The molecular weight of x is 16 times that of y. Then :

Options:(select one or more)

Answer:

A, B

Solution:

Average KE per molecule $= \frac{f}{2} k T$ : same at same $T$ .

$v_{r m s} = \frac{3 RT}{M}; M_{x} = 16 M_{y} \Rightarrow v_{x} = \frac{v _{y}}{4} .$

Pressure needs mole numbers, which are not specified.
