Avogadro s Law: The Volume Amount Law

Avogadro s Law: The Volume Amount Law
Gives the relationship between volume and amount when pressure and temperature are held constant. Remember amount is measured in moles. Also, since volume is one of the variables, that means the container holding the gas is flexible in some way and can expand or contract. 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.
V n
As before, a constant can be put in:
V / n = C
This means that the volume-amount fraction will always be the same value if the pressure and temperature remain constant.
V1 / n1 = V2 / n2 = V3 / n3 etc.
The Combined Gas Law
Now we can combine everything we have into one proportion:
The volume of a given amount of gas is proportional to the ratio of its Kelvin temperature and its pressure. Same as before, a constant can be put in:
PV / T = C
As the pressure goes up, the temperature also goes up, and vice-versa. Also same as before, initial and final volumes and temperatures under constant pressure can be calculated.
P1V1 / T1 = P2V2 / T2 = P3V3 / T3 etc.
