Question

At constant temperature gas is at pressure 540 mm hg at what pressure its volume decrease to half?​

Answer 1

Initial pressure (P1)=540mm of Hg
Initial Volume (V1)= X
Final Volume (V2)= (X - ½X) = X/2
Final Pressure= ?

Using Boyle's Law
[ Temperature is constant]

P1 × V1 = P2 × V2
=) 540×X = P2×X/2
=) 1080 = P2
