# Why does Avogadro's principle hold true for gases that have large particles and also for gases that have small particles?

Jun 14, 2018

the kinetic energy of a large particle and a small particle are the same at the same temperature

#### Explanation:

$K e = \frac{1}{2} m \times {v}^{2}$

A large particle is like a mack truck it may not move very fast because of its mass and inertia but it makes up for the lack of velocity with its heavy mass

A small particle is like a sports care it may not have much for mass but it has a very fast velocity. The velocity squared makes up for the small mass.

temperature is a measure of kinetic energy so all particles regardless of their size have the same kinetic energy at the same temperature.
