| Distillation is defined as: `Distillation is based on the fact that the vapor of a boiling mixture will be richer in the components that have lower boiling points.Therefore‚ when this vapor is cooled and condensed‚ the condensate will contain more volatile components. At the same time‚ the original mixture will contain more of the less volatile material. Distillation columns are designed to achieve this separation efficiently.Although many people have a fair idea what “distillation” means‚ the

Conclusion According to research it is proven that before Lorenzo’s oil was developed‚ many teenagers especially boys died at a young age due to the accumulation of saturated fatty acids in the blood. Lorenzo’s oil consisting of oleic and erucic acids which reduces the level of VLCSFAs in the blood helped improve the nervous system of many boys and made them live longer. As proven in the movie‚ Lorenzo’s oil worked effectively as it helped Lorenzo recover and improved his nervous system. According to a study
