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

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.

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

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

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.

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); 0.520 L Initial pressure (Pi) - 1.56L Initial volume (Vi) -1.00 atm New pressure (Pf) - 3.00 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

Practice!
