Question

Which of the following statement(s) is (are) correct regarding the root mean square speed (urms) and average translational kinetic energy (EX) of a molecule in a gas at equilibrium? (mutidele (JEE (Advanced) 2019] () ) Choice Hums is inversely proportional to the square root of its molecular 1? mass. av 3) Ea is doubled when its temperature is increased four times. ) urms is doubled when its temperature is increased four times. 1) Eav at a given temperature does not depend on its molecular mass. Youm:8 3RT Mi ​

Answer 1

The correct options are

A

U

r

m

s

is inversely proportional to the square root of its molecular mass

C

U

r

m

s

is doubled when its temperature is increased four times

D

E

a

v

at a given temperature does not depend on its molecular mass

We know that,

U

r

m

s

=

M

Hence,

U

r

m

s

is doubled when its temperature is increased four times and

U

r

m

s

is inversely proportional to the square root of its molecular mass.

E
