Avogadro's Gas Law

Avogadro's Gas Law
The Volume Amount Law
This law deals with the relationship between volume and amount when pressure and temperature are held constant.
Amount is measured in moles. Since volume is one of the variables, that means the container holding the gas is flexible in some way or another, and can expand or contract as the amount of gas within it is adjusted.
To put it simply, 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.
So where can we find a real-life example of this?
Real-life examples of this law at work:
Lungs
Tires
Balloons
Cells infected with the Ebola virus would be a good example, if that dealt with gasses.
My demonstration
Balloons!
As you can see, a blown up balloon has much more volume than an un-blown up balloon.
The more CO2 you push into the balloon, the more volume the balloon has. The container the gas is in expands as more gas is added.
Big Picture Concept:
the concept here is systems and system models. The system under scrutiny is the Gas Laws. "Although gases are not ideal, the ideal gas law allows us to understand the concepts of volume, temperature, pressure and concentration." -lesson 4.2
In learning about the Gas Laws, we are provided tools for dealing with them, such as the ideal gas law equation, which we can use in many different ways to make various calculations regarding gas and how it is effected by pressure, volume, temperature, amount, etc.

Information was what I learned in the modules and what I took down in my science notebook
