Boyle's+Law.Bertino

=Cameroons's Law= Robert Boyle created the law in 1662. Boyle discovered the relationship between pressure volume when two of his colleges brought it to his attention. He ran several experiments on it.One of these tests showed that as the pressure of a gas is doubled the volume reduces by one half. This is explained with the relationship between volume and pressure. As the volume decreases or increases accordingly the particles either have more or less room to move, and if they have more room to move the pressure will decrease and will increase if the volume is reduced.

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

The law is written as: where: P= pressure V= volume k= constant value that represents the pressure and the volume

To solve a problem using pressure and volume the extended equation of would be used. In this equation P1 and V1 are the beginning conditions and P2 and V2 are a different set of conditions. P1= initial pressure P2=different/changed pressure V1=initial volume V2=different/changed volume

If you have a sample of nitrogen has that takes up 110 mL of volume when its pressure is at 2 atm. What will the volume of the gas be if it is at 2.5 atm of pressure. -First you have to fill in your variables [P1=2atm, P2=2.5atm, V1=110ml, V2= missing mL -Second you have to turn the equation so that you are able to find the missing variable(V2) __P1V1__ = V2 P2 -Third you have to fill in the variable in the equation __(2atm)(110mL)__ (2.5atm) -Fourth calculate the final answer: V2= 88mL
 * Sample Problem**:

This graph shows the relationship between volume and pressure. As the volume increases the pressure decreases.
