P1V1 = P2V2 supports ?

A.

Charles’s law

B.

Boyles’s law

C.

Graham’s law

D.

Avogadro’s law

Correct answer is B

V = 1/P

cross multiply

K = VP

V1P1 = V2V2

For a fixed amount of an ideal gas kept at a fixed temperature, pressure and volume are inversely proportional. Or Boyle's law is a gas law, stating that the pressure and volume of a gas have an inverse relationship, when temperature is held constant.
The equations supports only Boyle’s law. Option A,C,D are not in support of the equation...
