surface area vs rate of time Introduction: In the investigation an experiment is conducted investigate if the breaking of alka seltzer into ½, ¼ and none effect the time it dissolves. The context of the problem is the time it dissolves to have the medicine show its effect. This problem exist in real life as people take alka seltzer to relief heartburn, acid digestion and stomach aches.…
Introduction: Kidney stones, also known as renal lithiasis, are a common urinary tract disorder that often results from concentrated crystallized minerals in the urine. These minerals can include anything from calcium oxalate, calcium phosphate, to uric acid. Since the kidney stone has to travel through the urethra, it can be extremely painful depending on the size and shape. There are however many preventative actions to combat the formation of kidney stones. Most people have their own home remedies that have stemmed from generations of cultural beliefs, but how practical can a home remedy be?…
Who was Otzi? Why was he murdered? How was he murdered? What happened? Those are all questions trying to be answered.…
I. Science fair Question What material will make ice melt fastest? II. Background Research Did you ever wonder what makes ice melt fastest? This research paper is going to talk about how ice melt works.…
“Miracle on Ice” On February 22, 1980 history was made. In the midst of the tensions between the United States and the Soviet Union, Team U.S.A managed to beat the U.S.S.R. team in a fierce hockey game during the XIII Winter Olympic Games. Due to the numerous American defeats throughout the entirety of the Cold War, ranging from the conflicts at Vietnam, the U2 incident, and the vast spread of communism, “The Miracle on Ice” boosted American morale towards the fight against the Soviet Union at a time when they needed it most.…
The Battle on the Ice was a brief battle that is best known for the fact that it was mainly fought on a lake that was frozen solid. The battle gained this title from the unusual battleground that was used, but it can also be referred to as the Battle of Lake Peipus. The fight between Russians and Estonians took place at the two countries central border of Lake Peipus on April 5, 1242, and ended that same day. The geographical factors found in this battle make it one of the most impressive in history.…
Sungwoong Lee My brother and I watched the film Chasing Ice together on Wednesday. I watched all of the trailers that were on the list. However, among those 5 films of the list, I decided to watch the Chasing Ice because the scenery of Arctic was magnificent and I’m also interested in topic of global warming and wanted to know more about how the global warming affects to the glaciers in Artic.…
The modern production management was what Ice-fili lacked. With plenty well trained managers Nestlé could leverage this advantage to produce relatively high quality ice cream with a lower cost. Using locally supplied component further reduced the cost of production. Its long presence in Russian ice cream market and strong marketing ability generated a strong preference among Russian customers. Its abundant experience on distributing enabled its strong control over the channels and massive coverage over the whole market.…
Since most of the human body is made of water and by lowering the body below the freezing point of water will result in massive ice formation. Cryonic facilities can’t simply put patients into a vat of liquid nitrogen because their cells would freeze and simply shatter. Because of this reason, patients are protected from ice damage by using a mixture or agent (sort of a human antifreeze) to reduce, or even eliminate, ice formation. Conventional bypass technologies are used to circulate the solution throughout the body. When enough water is replaced with the agent, the patient is maintained at cryogenic temperatures for long-term care.…
Does the type of liquid affect how fast an ice cube melts? Does the type of liquid affect how fast an ice cube melts? In an experiment (not ours) involving three liquids, pop melted the ice within it the fastest out of the three. Molecules cause ice to melt in a pretty simple way. When salt is thrown on snow or ice, it prevents the ice or snow from freezing over once again.…
The theoretical concepts that underlie the Hot Ice experiment involve a supercooled, supersaturated aqueous solution becoming a solid. When a liquid is cooled beyond its freezing point but remains liquid is known as supercooling or undercooling, and being supersaturated occurs when the solutes in a solution exceed the saturation point. The sodium acetate in a supercooled state will rapidly change into a solid with the addition of physical energy or a nucleation site. During the transformation of the liquid supercooled solution into solid crystalline formation produces heat in an exothermic reaction, hence the name hot ice.…
Investigative Question Does sugar or salt effect the freezing point and period of time that water takes to freeze? Hypothesis If you add either sugar or salt to water it will affect the freezing point of the water and will therefor take longer to freeze. Aim…
During the entire lab, the main purpose was to, Identify the given unknown salt through a variety of experiments which yielded valuable quantitative and qualitative data. Before any experiments were carried out, multiple properties were compiled in order to have a source to compare the found results with. Beginning with the first experiment to determine if the unknown salt was hygroscopic, efflorescent, deliquescent or none of the above properties. This test was done through weighing an amount of the salt and reweighing after 15 minutes which would show if the salt had one of the above properties (either by gaining mass from the air, losing mass to the air, turning to solution) or none of the properties. Furthermore, tests were done to identify…
Dissolve all the potassium nitrate while continuously stirring. 8. Once dissolved, let the contents cool and once again record the temperature at which crystal form. 9. Repeat this process for a total of five trials.…
The Calorimetric Determination of Enthalpy and Entropy Changes of the Thermal Decomposition of Sodium Sulphate Decahydrate Abstract Sodium sulphate decahydrate thermally decomposes to anhydrous sodium sulphate at 50⁰ C and cools to form anhydrous sodium sulphate. Using Hess's Law the enthalpy and entropy changes of this process can be determined in order to deduce the spontaneity of the reaction. The transition temperature was determined by melting the hydrated crystals at 50⁰ C and allowing them to cool until a constant temperature was reached. The molar enthalpy and molar entropy changes were determined using calorimetric principles. Different weights of both decahydrate and anhydrous crystals were added to water and the temperature changes…
