Real World Applications – Algebra I
Boyle’s Law states that the pressure and volume of a gas are inversely proportional. Looking at the picture on Wikipedia, we can see this relationship.
http://en.wikipedia.org/wiki/File:Boyles_Law_animated.gif What does this mean? How does this represent an inversely proportional relationship?
A bicycle pump is a great example that shoes Boyle’s Law. When you push down on the pump, the volume inside the bike pump decreases, and the pressure of the air increases so that it’s pushed into the tire.
If we were to substitute any value for the pressure, the output is also changing. As the pressure increases, the volume decreases.
Now let’s take a look at a graph that demonstrates this relationship.
What other physics-related topics demonstrate inverse variation models? How do you see this in everyday life?
