# Boyles Law

Now we know: `(P_1\ \ V_1)/T_1=(P_2\ \ V_2)/T_2`

and we know Boyles `=` Temperature constant

If we choose ONE for the value of `T`

**NOTE: **It doesn't really matter what value you choose they will cancel each other out being the same.

`(P_1\ \ V_1)/1=(P_2\ \ V_2)/1`

is the same as

`P_1\ \ V_1=P_2\ \ V_2`

This is Boyles law
