# Boyle's Law

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

and we know Boyle's law = 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

then  (P_1\ \ V_1)/1=(P_2\ \ V_2)/1

is the same as

P_1\ \ V_1=P_2\ \ V_2

This is Boyle's law
