particles

[lozzy_seward]

if something has more particles what does this mean... is there any equations to support this

[fo3nix]

I don't understand what you mean; can you describe further?

If something has more particles, then there's more of it.

particly if it has a lot more :-?

In the case of gasses there is a formula known as the gas equasion.

PV=nRT

Pressure times Volume equals the number of particles times the Gas Constant times temperature in Kelvin.

Essential for a given pressure and temperature there is always the same number of molecules present is a specific volume of gas regardless of the type of molecule.

Hence the density of a gas is always proportional to the molecular weight.
