Boyle's Law states that as __**pressure increases**__ in a gas, **__volume decreases!__** (Simply: As P↑, V↓). In 1662, Robert Boyle discovered that gas pressure and volume are related in mathematical terms. Boyle found out that increasing the pressure of a gas by 2 at a constant temperature, reduces the volume by half. This is the basis for his law.

**__Equation:__**

 * P 1 V 1 =P 2 V 2 **

P=Pressure V=Volume

__**Units**__: __Pressure:__ atm __Volume:__ L

__**Example problem**__:
__**Q:**__ //Find the __final volume__, in Liters, using Boyle's Law and the following info:// P** 1 **=4atm V** 1 **=2L P** 2 **=8atm V** 2 **=?

__**A:**__ 1) **Write down formula:** P 1 V 1 =P 2 V 2

2) **Plug in numbers:** (4atm)(2L)=(8atm)(V 2 )

3) **Solve for V 2 using Algebra (divide by 8atm on both sides):** (4atm)(2L)/(8atm)= (8atm)(V 2 )/(8atm)

4) **Multiply and divide** **(the atms cancel, so you're left with L)**: (4)(2)/(8)= 1L

5) **You're done!** V 2 =1L
