Boiling

Chemistry Internal Assessment Introduction: The experiment is to conclude which aqueous solution of the chlorides has the highest boiling point out of the five that has been tested.there will be five different chloride compounds mixed into water and be heated till it is boiling. The interest for this topic comes from how intermolecular forces affect the molecules by either repulsing and attracting molecules due to polarity. This idea interests me because when cooking and boiling salt water, it takes longer and for it to boil as well as mixing anything else into the water. Research Question: How does different chlorides affect the boiling point of water? Background research: When a solute is added to water the boiling point of the water gets higher. This is the boiling point elevation. The cause of this is vapor pressure. The vapor pressure of the solvent is less than the vapor pressure of the pure solvent (water). The boiling point of the solution would need to be heated to a higher temperature to be equivalent to the external pressure. Different solutions will have different vapor pressure. When adding a solution to water the boiling point is elevated and the temperature would need to be raised to boil the solution. Methodology: For this experiment the independent variable would be the solute that is being…

The boiling point of an organic compound determines its structural features and physical properties of the compound, which helps us to name the characteristics. Boiling point defined as the “temperature at which the vapour pressure of the liquid is the same as the pressure of the atmosphere on the liquid surface”. (Mahaffy, P, Bucat, B, Tasker, R, Kotz, J, Treichel, P, Weaver, G, McMurry, J 2011). The boiling point 1-hexanol, 2-hexanone, 1-pentanol and 3-methyl-1-butanol are represented in the…

2.3.1 MAJOR PROCESSES 2.3.1.1 THERMAL PROCESSES (DISTILLATION) Around half of the world’s desalted water is produced with heat to distill freshwater from seawater. The process of distillation mimics the natural water cycle in that saline water is heated, producing water vapor that condensed to form freshwater. In an industrial plant or laboratory, water is heated to reach the boiling point to produce the maximum water vapor amount. To make it economically in a desalination plant, the…

He accomplishes this rhetorically through making logical arguments that show a possibility of lobsters feeling pain, and counter local rebuttals that propose false premises about the nature of lobsters. And adds his own emotional appeals in his own experiences with boiling lobster and experiencing the festival. While diving into reasoning on both sides of the argument Wallace makes logical arguments to reveal the possibility for lobsters experiencing excruciating pain. At the same time, he pulls…

a smooth ball. Wrap up the dough and allow it to sit for about a half hour. After allowing the dough to process, you now need to create the noodle. Roll out the dough until it becomes about 1/8-inch-thick. Then cut the sheet into pieces that are 12 inches long and 3 inches in width. Bring water to a boil as you’re doing this step. Place the cut strips into the pot of boiling water. Precook the noodles in appropriate sized batches so that they do not stick to one another. Allow the noodles to…

In “Consider the Lobster,” published in Gourmet magazine in 2004, David Foster Wallace, an American novelist, essayist, and college professor, addresses the ethical considerations that revolve around the annual Maine Lobster Festival- eating lobster. This festival attracts tourist from all over the country to enjoy live music, beauty pageants, cooking competitions, and of course lobster (236). The easiest way to prepare lobster is boiling it in a kettle, and an important detail of this process…

you have a horn that is already cored (already hollowed), then you can skip to the next step (Cleaning the Horn). Boil the horn for 5 to 7 hours, depending on thickness and size. The time needed to boil will vary, so don 't forget to keep checking on it. Just as one cow is different from the other, so are their horns. boiling horn Make sure horn is completely submerged in boiling water Make sure the horn is completely submerged in water when you boil it. Be sure to put something on the…

Granted, the boiled water doesn't taste any different if it was boiled by a cheaper kettle, in fact the litre capacity of 1.5 is significantly inferior to the standard measure of 1.7; albeit, who uses every drop every boil - granted, there's a valid point of eco-friendliness with the artisan kettle though. I guess, the overall gauge is knowing what kind of boiling water experience you want and can afford. My version is white, the red would needlessly shout at me in an ambiance soft lit kitchen…

He then started worrying about his dog when he heard a yell from a distance. He ran towards that voice and saw a group of people surrounding a body on the ground. He got closer to get a better look, but then he realized that it was his beloved friend, Truffle. His co-worker told him that he had many major burns in his mouth from the boiling water, and third degree burns on his body from the fire. He was also too fatigued to even breath. Devin started screaming and bawling on Truffle’s corpse, he…

Haiti Water Project Haiti has been affected by natural disasters. and loss of natural resources. Heat and electricity is scarce which means foods are difficult to prepare. Cooking is complicated because the loss of resources such as fresh water and crops. Using the solar oven to boil fresh water will help many people cook different meals and support themselves. Boiling the water will kill the bacteria and make the water consumable. The purpose of the invention is to boil…
