The pressure P, of a gas varies inversely with its volume, V. Pressure is measured in units of Pa. Suppose that a particular amount of a gas is initially at a pressure of 84 Pa at a volume of 36 L. If the volume is expanded to 216 L, what will the new pressure be? I don't just want the answer! I want to know how to solve this problem if possible.

answer is 28 pa just took the test. and I have all the answers if anyone needs them for connections academy. ;)

P1*V1 = P2*V2 P2 =( 36*84)/216 P2= 14 Pa
