1. The average translational energy and the rms speed of molecules in a sample of oxygen gas at 300 K are 
and 484 m / s respectively. The corresponding values at 600 K are nearly (assuming ideal gas behaviour)
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
but 
i.e. if temperature becomes twice then energy will becomes two time
i.e. 2 × × 6.21 × × 10 –21 = 12.42 × × 10 –21 J
But rms speed will become 
times i.e. 
.
