Africtionless piston-cylinder device contains 10 kg of water at 20°c at atmospheric pressure. an external force f is then applied on the piston until the pressure inside the cylinder increases to 80 atm. assuming the coefficient of compressibility of water remains unchanged during the compression, estimate the energy needed to compress the water isothermally. take the water in the cylinder as the system.
