As reading chapter 22 James continues his Explor of Suffolk, he was more involved in pain in his discovery. James did not want to enter the synagogue because of his Jewish roots that were supposed to say to other children. “Aubrey used James's tape recorder to send a greeting to Ruth, but James never played it for her, thinking it might be too painful.(McBride 225) ” Aubrey Runestein, the father who had taken over the Shilskys store when Ruth's father left town. All James wanted to do is get more information about his mother.…
To begin my experiment, I will buy kosher salt, sea salt, iodized salt, table salt, rock salt, and Styrofoam cups from Walmart, Winn Dixie, or Fresh Market. For consistent samples and to ensure no variations that could change results, instead of taking cubes of ice from a freezer, I will freeze exactly one cup of water per batch of…
Press a warm quarter firmly against a chunk of dry ice. The quarter will scream loudly as the heat of the quarter causes the dry ice to instantly turn to gas where the two make contact. The gas pressure pushes the quarter away from the dry ice and, without contact, the dry ice stops sublimating. The quarter falls back into contact again, and the cycle repeats. This happens so quickly that the quarter vibrates, causing the singing sound.…
Salt is used on a daily basis for a number of reasons, such as cooking, water treatment and de-icing roads.[1] In Canada, salt is heavily relied on when it comes to snow removal. But, the truth is, while salt does help people during the winter, it causes the rest of the environment to suffer. Because of this, I strongly feel that salt should NOT be used on our roads. Salt harms animals, affects aquatic ecosystems negatively, causes pollution, contaminates greenery by the road, and damages cars and roads.…
Where does Ice come from? Ice is usually manufactured in China but is sometimes transported to Australia via other Asian countries such as the Philippines or Indonesia. Australia has seen much more ice being imported into the country in recent years. How many people use Ice?…
Brandon Thai 5/17/17 Freezing Point Depression Abstract The freezing temperature of pure Cyclohexane and a solution of Biphenyl and Cyclohexane was determined. This was done by examining the temperature curves for each solution. The freezing temperature for pure cyclohexane was determined to be 7.3 degrees celsius and the mixture of Biphenyl and Cyclohexane was 2.07 degrees celsius.…
The freezing point of the cyclohexanol was about 17.7°C, and the freezing point for the unknown solute mixed into the cyclohexanol was about 6.2°C. So the approximate change in temperature of the two freezing points was about 11.5°C. With this calculated information, the found molar mass of the unknown solute B was about 278.4g/mol, which is close to given molar mass of octadecanol. Conclusion-…
In this experiment you will become familiar with the properties of dry ice while creating interesting effects. Most people know that dry ice is used for fog at parties or in movie scenes. Dry ice is also used for keeping things cold or frozen because of its very cold temperature at 109.3 fahrenheit below…
1) The song Cold Water has a lot relating things about me, would you like to see it?! lets begin. 2) Nobody is perfect, not everyone can wish what they want because you have to work for it.…
Conclusion: The general conclusion that I was able to produce about the effects of salt on the boiling point temperature of water is that with the addition of salt, the boiling point temperature of water increases. The results of the lab experiment do agree with my predictions and I can accept my initial hypothesis. However, I believe the data would be more consistent and solid had 2M and 4M of NaCl had been included in the experiment, rather than jumping from 1M to 3M to 5M. Discussion:…
Heat transfers from your hand to the ice. Salt makes ice cubes melt faster. The size of the ice cube also affects its melting rate. Ice melts faster when the air is moving. The chemicals may also change how long the ice cube takes to melt.…
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.…
Snow globes are made of clear glass, a transparent sphere with a scenic view and a plastic toy inside the globe. The sphere likewise encases the water in the globe; the water fills in as the medium through, where the snow falls. The globe must be shaken to actuate the snow so the white particles can fall gradually to reach the base. When the snowflakes/object falls, it experiences two external forces which are; the gravitational force and the aerodynamic (air resistance) drag of the object, which gradually brings the object down. Furthermore, the drag force affects the object because of the shape and the viscosity of the fluid.…

In 1929 the Morton Salt Works Company purchased all the surrounding salt mines, and began the excavation of the salt dome underneath the town of Grand Saline. With the newly discovered abundance of salt there were plenty of jobs to go around as The Great Depression began to settle upon the market. By the year 1945 there were 950 people employed by the mine in Grand Saline, and that number doesn’t include the transportation jobs that were created by the mine either. The added income in town from the jobs created allowed for the local prices to fluctuate without dropping as far as they had elsewhere.…
