Data: ρО3 – ozone density at standard conditions. (ρО3 = 2.1 kg / m3).
Const: Р – pressure at normal level (P = 101 325 Pa).
To find out cf. square the velocity of ozone molecules under given conditions, consider the formula: Vх = √ (3Р / ρО3).
Let’s calculate: Vх = √ (3Р / ρО3) = √ (3 * 101325 / 2.1) ≈ 380.46 m / s.
Answer: Wed square the velocity of ozone molecules, according to the calculation, is 380.46 m / s.
