# In Avogadro's Law what would happen to V if N is increased/decreased? And what would happen to n if v is increased/decreased?

Jan 21, 2014

If n increases, V increases.
If n decreases, V decreases.
If V increases, n increases.
If V decreases, n decreases.

Avogadro’s Law states that if P and T are constant, the volume is directly proportional to the number of moles.

V ∝ n or V = kn or

$\frac{V}{n}$ = k

This means that the volume divided by the number of moles will always be the same if the pressure and temperature remain constant. In other words, the V and n go up and down together.

If the amount of gas in a container is increased, the volume increases. If the amount of gas in a container is decreased, the volume decreases.

Conversely, if the volume of a container is increased, the amount of gas must also increase. If the volume of a container is decreased, the amount of gas must decrease.

You demonstrate Avogadro's Law every time you blow up a balloon and then let it deflate.
