# Charles Law

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

and we know Charles law = Pressure constant

If we choose ONE for the value of P

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

(1xxV_1)/T_1=(1xxV_2)/T_2

is the same as

V_1/T_1=V_2/T_2

This is Charles law
