Question

at constant temperature a gas is at a pressure of 1080 mm Hg. if the volume is decreased by 40% find the new pressure of gas

Answer 1

Tnwramit1 Maths AryaBhatta
Given

Process=> constant temperature

So

Pv=nrt


Nrt= constant

P1v1= P2v2-------(1)

Data Given
Volume decrease by 40%
Let initial volume =v1

Final volume = 0.6v1

Pressure (p1) =1080 mm of hg

Putting the values in equation 1, we get

1080xv= p2x0. 6v1






Final pressure (p2) =1800 mm of hg
