INTRODUCTION In the cloud point experiment‚ waxes will appear and thickens the oil and clogs fuel filter and injectors in engines. The wax also accumulates on the cold surfaces and forms an emulsion with water. The appearances of cloud point determine the first cloud of wax crystals in a liquid when it is cooled. Whereas‚ pour point experiment is to determine the minimum temperature of the oil which will continue

The phrase “turning point” has a lot of meanings but personally‚ for me‚ it is a moment that caused me to realize what has always been in front of me. Turning point may also mean a time at which a decisive change in a situation occurs‚ especially one with beneficial results. Recently‚ one event became the turning point of my life and my beliefs.

Chem 234 02/17/13 Lab 2: Melting Points Purpose: To determine the purity of a substance using melting point as physical property. We must also learn how to identify an unknown compound using its melting point. We got to identify an unknown compound using mixture melting point and finally we must learn to obtain an accurate melting point using Mel-Temp apparatus. Procedure: Set voltage to obtain the desired heating rate at the anticipated melting point range. The voltage control controls

idea by adopting it themselves and spreading the word. The attainment of the tipping point that transforms a phenomenon into an influential trend usually requires the intervention of a number of influential types of people. In the disease epidemic model Gladwell introduced in Chapter 1‚ he demonstrated that many outbreaks could be traced back to a small group of infectors. Likewise‚ on the path toward the tipping point‚ many trends are ushered into popularity by small groups of individuals Gladwell

On pages 20 and 21 of the book‚ Gladwell tells of two different men that
