Simple Distillation Experimental Organic Chemistry: A Miniscale and Microscale Approach. 4th Edition. By Gilbert and Martin. Section: 4.4 Introduction: Distillation is a technique used to purify various liquids. In a simple distillation‚ a liquid is boiled and the vapors work through the apparatus until they reach the condenser where they are cooled and reliquified. Liquids are separated based upon their differences in boiling point in which each pure substance is at least greater than 40-50

described by the vapor pressure of the liquid. The vapor pressure is the pressure that the molecules at the surface of the liquid exert against the external pressure‚ which is usually the atmospheric pressure. The vapor pressure is a very sensitive function of temperature. It does not increase linearly but in fact increases

M. Velas FUNCTIONS OF LEISURE Relation to Increased Production and Consumption The function of leisure is largely determined by the kind and amount of free time and by the ideas of the age. When spare time consists of short breaks between long periods of sustained labor‚ its function is thought of as recreation – relaxing the worker so that he can work more efficiency after the break. When the goals are efficiency of work‚ increased production‚ more power and more wealth‚ the function of leisure

Simple Machines Definitions: Machine- A device that makes work easier by changing the speed ‚ direction‚ or amount of a force. Simple Machine- A device that performs work with only one movement. Simple machines include lever‚ wheel and axle‚ inclined plane‚ screw‚ and wedge. Ideal Mechanical Advantage (IMA)- A machine in which work in equals work out; such a machine would be frictionless and a 100% efficient IMA= De/Dr Actual Mechanical Advantage (AMA)- It is pretty much the opposite of

specified at standard pressure. The boiling point of a substance is the temperature at which the vapor pressure of the liquid equals the pressure surrounding the liquid and the liquid changes into a vapor. In this experiment we were be able would use various apparatus to determining the melting point and boiling point of organic compounds. We realized that boiling point and melting is affected by pressure‚ molecular weight‚ structure‚ intermolecular interactions and most of all impurities present in

“The simple gift” written by Steven Herrick is narrated in the first person in helps to gives a sense of subjective‚ since it has the character’s own prejudices and preferences such as “I knew it was hunger”. It engages the reader by building up the closeness with them‚ and allows them to delve into the mind of the characters. “The simple gift” is also written in a diary format as from the three different characters points of view‚ in affect to be more personal and sincerely. This is the main technique
