Well, what is #"Boyle's Law...?"#

Explanation:

#"Boyle's Law..."#, which is an EXPERIMENTAL gas LAW...holds that at constant temperature, and constant quantity of gas, #Pprop1/V#...where #prop# means #"proportional to...."#...

And so #P=k/V#...and #k=PV#...but this HOLDS for pressures and volumes given the STATED boundary conditions....

And thus the normal expression of #"Boyle's Law..."#, #P_1V_1=P_2V_2#....

And when we graph pressure against volume for a given quantity of gas at constant temperature....we gets...
