first used in Texas. These wells range from hundreds to thousands of feet deep (Source 3). Production wells may be drilled in the vertical direction only. But they can be paired with horizontal or directional sections (source 3). When the injected liquids pressure exceeds that of the rock, the fluids open or enlarge fractures that can extend several hundred feet away from the well (Source 3). After the fracturing is completed, the internal pressure of the geologic formation causes the injected…

them steep for 7 - 10 minutes with a watch glass on the top and the heat on low. Excessive heat can decompose caffeine so do not let the tea dry out. 2. Squeeze the tea bag against the side of the beaker with a stir rod to remove as much of the liquid as possible. Let the solution cool to room temperature. 3. Pour the tea into the separatory funnel. (Make sure that the stopcock is closed). Add about 10 to 20 ml of methylene chloride and shake gently. Vigorous shaking will lead to an…

of some organic compound during filtration. Another reason for such a low percent recovery could be due to the drying agent. If the drying agent is added in large amounts it could lead to losing of the organic solvent by adsorption of the organic liquid. A better experimental result would show much higher percent recovery than the ones obtained. Obtaining a 100% recovery means that nothing was lost in the process. Also, the compound could have been impure and/or contaminated and so yielding…

and a fast blast stain. The EcoRl restriction enzyme is the enzyme that was used in order to cut the DNA at specific sites into many separate fragments. A centrifuge is a machine that uses a rotating container inside it in order to force all of the liquids to the bottom of the test tubes within the container. A water bath is a heated bath of water which is usually set at a specific temperature that is used to heat up substances. The DNA loading dye was used in order to visually see the DNA…

collected shows that my hypothesis was correct because the average number of the different amounts of salt was higher than the last one. Water boils when the molecules are able to overcome the vapor pressure of the surrounding air to move from the liquid phase to the gas phase. With that being said when you add salt that increase the amount of heat needed for water to make the transition( chemistryabouteducation). The more salt you add to water, the more you raise the boiling point. For control…

correlation between different types of salt and the final height of ice cream formations. Background Information Milk is made up of triglycerides (mainly milkfat) dispersed throughout water as an oil-in-water emulsion, or dispersion of globules of one liquid into another. When agitated, the emulsion begins to break down, or coalesce, into fat and water. However, during this process, air is beaten into the emulsion, creating a foam (Rohrig, American Chemical Society). While the ice cream…

Paintball is a game that shoots out markers or paintballs, that when they hit, the markers explode causing a paint mark on a person, a piece of cover, and trees.Paintball is also a game where many people do different types of games like capture the flag to different battle scenarios. Before paintball was a game paintballs was used to mark cattle for shipping purposes. Many people play this game with pump guns. These guns have an air pump attached and also a hopper.The hopper is the top piece of…

The optimum dental treatment for any patient is to restore teeth function and esthetic while removing the least amount of tooth structure, and replacing it with a dental material that will be biocompatible with the tooth and resist the hostile oral environment. Dental materials are incorporated into the teeth structure by retention. This retention can accomplished through mechanical, chemical adhesion or bonding mechanisms between materials and the dental structure. Mechanical retention is…

satisfying and relaxing. You also might know this a silly putty or goo. It is unique because it has properties of both a liquid and a solid. The Science The science behind this slime is awesome! A unique polymer, this slime is made mostly out of glue. Because of the glue’s long and flexible molecules, the slime has properties of both a liquid and a solid. A borate ion is formed by mixing borax in water. When the borax solution is mixed into the…

Procedures Independent Variable An independent variable is a variable that remains unchanged and stands alone. My independant variable is each hand cleaning product used. Organic Care orange and ginger antibacterial hand wash, Palmolive antibacterial liquid soap, Dettol hand wash - foam and Dettol hand sanitiser. Dependent Variable A Dependent variable is a variable that is being measured in the experiment. My depenedent variable is the rate of bacteria deterioration (zone of inhibition).…
