Question

A vessel of volume ‘V’ contains an ideal gas at a pressure ‘P0 ’. The gas being removed from the vessel by means of piston pump with single stroke  by volume V4  . The pressure of the gas inside the vessel after 3rd stroke of the piston is 

Moderate
Solution

Applying Boyle’s Law

PoV=P1V+V4

P1=Po×45

P1V=P2V+V4

P1=5P24

P2=4P15=454Po5=16Po25

After 3rd stroke 64Po125
