Question

at what temperature will oxygen molecules have same rms speed as helium molecules at S. T. P
​

Answer 1

Answer:

300 K

The temperature at which oxygen molecules have the same root mean square speed as helium atoms have at 300 K is: (Atomic masses : He=4u,O=16u)

Answer 2

Answer:

300 K

The temperature at which oxygen molecules have the same root mean square speed as helium atoms have at 300 K is: (Atomic masses : He=4u,O=16u)
