Question

At a constant temperature, a certain mass of gas occupies 7.5 lt when the pressure is 800mm of Hg. Calculate the pressure at which the volume of the gas would be decreases by 35% of its initial volume.

Answer 2

Answer:

1230.76 mmHg

Explanation:

according to boyle's law at const. temp.,

Pressure is inversely proportional to the v

olume

P1V1=P2V2

P1=800mmHg

p2=?

V1=7.5l

V2=35%of v1

ie, 65/100*7.5

therefore, p2=800*7.5/4.875

=1230.769231

And here is the answer:)
