Question

The temperature at which rms velocity O2 molecule is same as helium molecules at STP.​

Answer 1

Answer:

The temperature is 2400 K for which the RMS speed of O2 molecules is same as speed of helium molecule at STP

Explanation:

As we know that RMS speed of ideal gas is given as

$v_{rms} = \sqrt{\frac{3RT}{M}}$

now for STP condition RMS speed of helium is given as

$v_{rms} = \sqrt{\frac{3R(300)}{4}}$

now let say the temperature of oxygen molecule is T

so we will have its RMS speed as

$v_{rms} = \sqrt{\frac{3RT}{32}}$

now both the gases have same speed so

$\sqrt{\frac{3R(300)}{4}} = \sqrt{\frac{3RT}{32}}$

now we will have

$\frac{300}{4} = \frac{T}{32}$

$T = 2400 K$
