# Why does a balloon of 2*L volume contain TWICE as many gaseous particles as a balloon of 1*L volume under equivalent conditions of pressure and temperature?

Would you not expect this outcome?

#### Explanation:

And this relationship was experimentally confirmed by Amadeo Avogadro. The volume occupied by a gas is directly proportional to the number of gaseous molecules present in the container:

${V}_{1} / {n}_{1} = {V}_{2} / {n}_{2}$, where $n$ is the number of gaseous particles.

Historically, this gas law was important because it led to the idea of molar equivalence, and $\text{Avogadro's number.}$

Certainly, this is the behaviour we observe when we blow up a balloon.
