WebMaxwell-Boltzmann Distribution of Speeds. The distribution function for speeds of particles in an ideal gas at temperature T is. f ( v) = 4 π ( m 2 k B T) 3 / 2 v 2 e ( − m v 2 / ( 2 k B T)). The factors before the v 2 are a normalization constant; they make sure that N ( 0, ∞) = N by making sure that ∫ 0 ∞ f ( v) d v = 1. WebMaxwell-Boltzmann Distribution of Speeds. The distribution function for speeds of particles in an ideal gas at temperature T is. f(v) = 4 √π( m 2kBT)3/2v2e−mv2/2kBT. The factors before the v2 are a normalization …

The difficulty in answering your question is what you mean by the velocity of the particles in a liquid. In a gas the mean free path is long compared to the size of the particles, so the motion of the particles is well described as simple translational motion in a straight line with occasional changes of direction due to collisions.
WebA 1.000-g sample of an unknown gas at 0C gives the following data: P(atm) V (L) 0.2500 3.1908 0.5000 1.5928 0.7500 1.0601 1.0000 0.7930 Use these data to calculate the value of the molar mass at each of the given pressures from the ideal gas law (we will call this the apparent molar mass at this pressure).
