The mean square velocity of the gas molecules is 700 m / s, the gas mass is 6 kg, the volume is 5 m3. determine the gas pressure.

These problems: Vav (mean square velocity of the molecules of the taken gas) = 700 m / s; m (gas mass) = 6 kg; V (the volume in which the taken gas is located) = 5 m3.
You can determine the gas pressure by the formula: P = 1/3 * ρ * Vav ^ 2 = 1/3 * (m / V) * Vav ^ 2 = m * Vav ^ 2 / 3V.
Calculation: P = 6 * 700 ^ 2 / (3 * 5) = 196 * 10 ^ 3 Pa (196 kPa).
Answer: The gas pressure is 196 kPa.
