A system of cylinder(one end open)and piston is held in horizontal position inside a vacuum chamber. the mass of the cylinder and that of the piston are m1, m2, respectively. The piston which has negligiblethickness dividesthe volume of the cylinder into 2 equal parts.The closed section of the cylinder contains n moles of helium which may be considered as an ideal monoatomic gas at T0=273 K. The piston is held at rest in the mid position and suddenly released. Determine the final velocity of the CYLINDER. Assume that the heat transfer between cylinder and piston, and the motion of the centre of gravity are negligible.T0=273Km1=0.6 kg, m2=0.3 kgn=25 molesCv of He =12.6 J/mol.KCp/Cv=5/3
