Question

Solve the 6th one, first person with correct explanation will get brainliest

Answer 1

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

    p2 =1080*v1/0.6v1

p2=1080/0.6

Final pressure (p2) =1800 mm of hg
