AM+BOYLE'S+LAW


 * Boyle's Law-** Boyle's law states that the volume of a gas increases when the pressure decreases at a constant temperature.

The mathematical equation for Boyle's law is:

To solve pressure-volume problems use the following equation:
 * P1V1=P2V2** and this depends on which variable you are solving for.

-Pick out all of the numbers in the problem and list them. Pressure 1: 20 atm Volume 1: 10 mL Pressure 2: 25 atm
 * __Example__**:You have a substance that started with a pressure of 20 atm & a volume of 10 mL in the beginning, the new pressure is 25 atm. What is the new volume of the substance?

Next you would figure out what you are solving for: Solving for Volume 2 Equation : P1V1/P2 = V2

Then plug in the numbers that belong with the equation.

20 atm x 10 mL /25 atm=V2 The atms cancel because there are two, so you know the final units are going to be mL


 * The answer comes out to be= 8mL**
