Brock+Boyle's

Boyles law says that when you decrease the volume a gas, then the pressure will increase. The equation for this is: P1V1=P2V2

For example if you half the amount of volume of gas, the pressure will double.

If you have a gas under 1 atm of pressure, in a 300 mL container, what would be the pressure of that same gas in a 150 mL container ?

1 atm x 300 mL = P2x 150 mL

To find P2, you must isolate it by dividing each side by 150 The equation will be:

P2 = __1 atm x 300 mL__ 150 mL

this becomes 300 mL over 150 mL, and the answer is: P2 = 2 atm.
