Question

Q. ] At what temperature will oxygen molecules have same rms speed as helium molecules at S.T.P.? (Molecular masses of oxygen and helium are 32 and 4 respectively).​

Answer 1

Answer:

T2=2400K

Explanation:

Solution is in given attachment..

Answer 2

$\sf V_{rms}$ of Oxygen = $\sf V_{rms}$ of Helium

• $\sf T_{O}$ = $\dfrac{273.15 × 32}{4}$

• $\sf T_{O}$ = 2185.2 K

• $\sf T_{O}$ = 2185.2 - 273.15

• $\sf T_{O}$ = 1912.05 °C
