Boyle’s Law : 

Boyle’s Law Relates pressure and volume # of molecules and temperature are constant If you cut the volume of a gas in half, what does that do to the number of collisions? What does that do to the pressure? Increases the # of collisions

Slide 2: 

We can use this relationship to help us determine a pressure or a volume. P1 x V1 = P2 x V2 Solve for the unknown value; the other three will be given to you in the problem.

Example : 

Example The pressure of 475.0 mL of gas is raised from 1.03 atm to 1.63 atm. What is the final volume of the gas? Rearrange by dividing both sides by P2 Substituting…

Example : 

Example If the volume of a gas changes from 3.41 L at 25°C to 7.39 L at 25 °C , and it begins at standard pressure (kPa), what is the final pressure? Rearrange by dividing both sides by V2 Substituting…
