# What type of particles are essentially independent of each other?

$\text{Gaseous particles...............}$
And a simple calculation you can do is compare the volume of $1 \cdot m L \left(\equiv 1 \cdot g\right)$ of liquid water, and that mass of water as a gas at $100$ ""^@C and $1 \cdot a t m$. You should try this out using $V = \frac{n R T}{P}$.
