| 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

PHY 114 Faraday’s Law of Induction Stephanie Scott Section: 10849 Group #3 Bochao Li 3/31/15 Abstract: The objective of the Faraday’s Law of Induction lab was to verify Faraday’s law of induction by measuring the emf generated in a small coil and comparing it with the calculated value. Secondly the goal was to investigate the relationship between the emf and the frequency of the driving signal. The magnetic field was found to be uniform throughout. For the frequency of 40 Hz‚ the average

Although Helium exists in the atmosphere of Earth in small quantities‚ it is one of the most common element in the universe. It is a rare gas on earth. Helium was first discovered by Pierre Janssen in the spectrum of the sun during an eclipse in 1868. It was shortly identified as an element and was named by the chemist Sir Edward Frankland and the British astronomer Sir Joseph Norman Lockyer. Helium has an atomic number of 2 and an atomic weight of 4.002602. Helium is represented by the symbol

Charles’ Law and estimate Absolute Zero In this IB Lab you will be assessed on the following criterion Conclusions and Evaluation Aim: Physics has many hundreds of laws and these can be tested in experiments to see if they are true. In 1787 the French scientist‚ J.A.C. Charles‚ published a law connecting the volume and temperature of gases. Your task is to see if you agree with his law. Another thing you have to consider is “ is my experiment accurate enough to prove or disprove the law ?“. It
