1. Boyle’s Law and Charles’ Law

2. What are these Laws all about?
These Laws Define the behavior of Gases.

3. Pressure
Defined as:
The amount of force exerted per unit of area. P=F/A
Pressure only occurs when the gas particles collide with another object.
The more collision the more pressure.
What are 2 ways to create more collisions? (Therefore more pressure)

4. To Create More collisions
Increase the number of gas particles.
Example: Air Pressure
Decrease the size of the container.
Example: Boyles Law

5. Boyles Law
If the Volume of a gas DECREASES, the Pressure of the gas will INCREASE, as long as the temperature does not change.
INCREASE Volume = DECREASE Pressure with Temperature CONSTANT.

6. Boyles’s Law Example:

7. Charles’ Law
The Volume of a gas will INCREASE as Temperature INCREASES as long as Pressure does not change.
Also true in reverse.

8. Charles’ Law Example

9. To Help you Remember:
Just think of: P T V
