What is the pressure of a gas if the mean square velocity of its molecules is 300m / s and its density is 1.35kg / m ^ 3?
| November 26, 2020 | education
Gas pressure is calculated by the formula
P = 1/3 * p * V ^ 2
Substitute by condition:
P = 1/3 * 1.35 kg / m ^ 3 * (300 m / s) ^ 2 = 40500 Pa
Answer: approximately 41 kPa
