Molecular velocity distribution

Molecular velocity distribution describes how the speeds of molecules in a substance vary at a given temperature. Because molecules are constantly moving in all directions, some are fast, while others are slow. This distribution shows the likelihood of a molecule having a particular speed—the most common speed corresponds to the peak of the distribution, while fewer molecules move very slowly or very quickly. It helps explain phenomena like diffusion and pressure, as the collective behavior of many molecules determines the properties of gases and liquids under different conditions.
