2. Definition of Law
States that the pressure and volume of a gas have an inverse relationship when temperature is kept constant
This is used to predict how a change in pressure will alter the volume of the the gas and the final pressure of the gas
That means that if the volume of a gas goes up the pressure goes down and if the volume of the gas goes up the pressure goes down

3. Boyle's law
This picture shows that when you increase the pressure on a gas, you decrease volume. Also, when you decrease the pressure on a gas, you increase the volume.

5. Explanation of video
In this video when pressure decreased and volume increased it remained constant
Though the ball compressed when front is blocked, increasing the volume
This shows how the boyle law is used and explains the inverse relationship between Pressure and Volume

6. Equations and variables
P * V = C
Pressure * Volume = Constant
P(initial) V (initial) = P(final) V(final)

7. Examples in real life
Bubbles exhaled when scuba diving grow as the surface of the ocean approaches.(The pressure exerted by the weight of the water decreases with depth, so the volume of the bubbles increases as they rise.)
Releasing a fluid through a syringe decreases the volume of air trapped under the plunger.

8. Example equation Remember to do Sigfigs! PiVi = PfVf
A gas occupies 1.56 L at 1.00 atm. What will be the volume of this gas if the pressure becomes 3.00 atm?
(1.56 L) (1.00 atm) = (3.00 atm) (x); L
Initial pressure (Pi) L
Initial volume (Vi) atm
New pressure (Pf) atm
New volume (Vf)- unknown (x)
Remember to do Sigfigs!
PiVi = PfVf
(1.56 L) (1.00 atm) = (3.00 atm) (? Vf)
1.56 = 3.00x
Divide
Final volume is 0.52
