By applying a pressure of 200 atm, you can compress water to 99% of its usual volume. Sketch this process on a PV diagram, and estimate the work required to compress a liter of water by this amount. Does the result surprise you?© BrainMass Inc. brainmass.com October 16, 2018, 1:10 pm ad1c9bdddf - https://brainmass.com/physics/system-work/work-done-to-compress-1-liter-water-by-1-201453
It shows how to calculate the work done to compress 1 liter water to 99% of its usual volume. It also sketches the compression process on a PV diagram. The solution is detailed and has a '5/5' rating.
