Answer 1

Answer:

20cm

Step-by-step explanation:

considering ideal gas situation and temperature being constant, Pressure*volume is constant

Now area of cross section of cylinder be A

therefore pressure = weight of piston/ A

initial pressure = 20*g/A

final pressure = 100*g/A

initial volume = 100*A

now we know p1v1=p2v2=constant

let final height be h

20*g*100=(100*g/A)*(h*A)

therefore h = 20 cm.
