Sublimation

Mary Shelly’s Frankenstein has characters that exemplify the Freudian psychoanalysis. The creature made by Victor embodies several aspects of his analysis: id, repression, displacement, and sublimation. The creature absorbed his surroundings and reflected them with how he ultimately felt about himself and his creator; the cultural surroundings of the creature best influenced his character. The creature, the yellow-faced and beautiful yet disgusting being, has had issues of feeling closer to a fish

extract caffeine from the solid black tea. This experiment involved two steps process; the first step includes solid-liquid extraction followed by the second step, which included liquid-liquid extraction to separate caffeine from water solution using sublimation. Procedure: Begin by emptying eight tea bags into a weighted boat and then weighting it. Add the tea, 150 mL of water and about 7 grams of calcium carbonate, which acts as a base to break the ester bonds in the tannin acid. The mixture was then

There are many other types of molecular organizations in solid water than we can talk about here.

purpose of this experiment is to demonstrate the isolation of a natural product from a biological source using extraction techniques, and to demonstrate purification by sublimation. We are isolating caffeine from tea. The goals of the experiment are to successfully extract caffeine from the tea solution and to further purify it by sublimation. We will find the percent yield and melting point of the caffeine at the end and we will also identify certain functional groups using an infrared spectroscopy and

In this experiment, we extracted caffeine from a tea bag. First, we had to convert protonated caffeine in tea leaves back to the free base form. So in a 30 mL beaker, we added 30 mL water and 2 g sodium carbonate and after boiling the water we immerged a tea bag in the hot water for about 5 minutes. After the tea bag was slightly cool we squeezed the tea bag to remove all water and caffeine using a funnel and back of a test tube. After that, we again brought the water to boil and immerged another

purposes. The quality and pricing of these military flags cannot be beaten, and they use digital printing methods to guarantee better quality. In addition to digital printing, you will also find that this company can do sublimation printing. Sublimation printing is where a dye-sublimation printer at the factory will use a computer printer that transfers dye using heat and prints it on materials like fabric, plastic, paper or cards. In most cases, military flags will be printed on fabric, but there are

Sublimation: I began playing Basketball freshmen year as a way to release my emotions and forget the thoughts that gave me stress or made me overthink. My coaches gave me the nickname of “Mean Darline” because of how tough and aggressive I would get when being on defense. Little did they know that I wasn’t good at that position because I loved Basketball but because it maintained me calm and allowed me to express myself in a socially approved activity. When the season was finished and I retired from

Hydration of Norbornene to Norborneol. Objectives: Used acid catalyzation to synthesize the norborneol product, then purified it with sublimation, performed a capillary tube melting point determination and an IR spectrum to characterize the product, and finally determined the stereoselectivity of the reaction.

us knowing. There are 8 different defense mechanisms. We use these mechanisms daily but probably do not even realize we do. These defense mechanisms include repression, denial, reaction, projection, regression, rationalization, displacement, and sublimation. I have interviewed my boyfriend and along with myself to identify some of these defense mechanisms. The four different defense mechanisms I have used in my life is denial, regression, displacement, and rationalization. The first one I have used
