What is the pressure of nitrogen if the mean square velocity of its molecules is 500 m / s and its density is 1.35 kg / m3?
Initial data: Vav (root-mean-square velocity of nitrogen molecules) = 500 m / s.
Reference values: according to the condition ρ (nitrogen density) = 1.35 kg / m3.
The nitrogen pressure is determined by the formula: P = ρ * Vav ^ 2/3.
Calculation: P = 1.35 * 500 ^ 2/3 = 112500 Pa (112.5 kPa).
Answer: The nitrogen pressure is 112.5 kPa.
