If we continue to heat the water we will begin to observe bubbles form and collapse on the bottom of the beaker. These are the precursors to true boiling. The water on the bottom surface of the beaker is heated to the point where it converts to vapor, but this vapor cools rapidly as ...
Networks (MLFN) model with 7 nodes (MLFN-7) is the best model to determine the initial boiling point of xylene mixed, with the RMS error 0.18; while the MLFN model with 4 nodes (MLFN-4) is the best model to determine the final boiling point of xylene mixed, with the RMS error ...
