Question

Calculate the temperature at which the average velocity of oxygen gas are all equal to 1500 $m s^{- 1}$ .

Open in App

Solution

Molar mas of oxygen gas is 0.032Kg/mole.

$U_{(} A v e r a g e) = \sqrt{\frac{8 R T}{Π \times M}}$

$1500 = \sqrt{\frac{8 \times 8.314 \times T}{3.14 \times 0.032}}$ .

$T = 3399 K$
