Question

At a constant temperature, a gas is at a pressure of 540 mm of Hg. At what pressure its Volume decrease to half ?

Answer 1

Answer:

1080mm

Explanation:

P1V1 = P2V2

V2=V1/2

now, P1V1= P2V1/2

P2 = 2P1

P2 = 2*540 = 1080mm

Answer 2

Initial pressure=540 mm Hg

According to Boyle' s law -

P1 V1= P2 V2

V2= V1/2

Now,

P1 V1 = P2 V2/2

P2= 2(P1)

P2= 2*540

P2 = 1080(And)
