Problem 4: Saturated liquid water at 1.0 MPa is throttled adiabatically to a pressure of 0.4 MPa. If the change in kinetic energy is negligible, how much water is evaporated at the exit of the throttling valve, in percentage

12000j is work done

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.

this would be about 43%
