Colorimeter Balloon Research Paper

The first part of the lab began by one lab member adding 10.0 mL of DI water to a test tube while another lab member obtained a beaker full of ice and salt. After both these steps were complete the test tube was put in the beaker full of ice. Immediately following the test tube be being placed in the beaker, a temperature probe was inserted into the test tube. The initial temperature was recorded and after the temperature was recorded in 30 second increments. Once the water exhibited supercooling and then remained consistent at .1 °C for 3 readings it was determined that the water had froze and formed crystals. Evidence that crystals formed allowed for it to be confirmed that the water actually hit freezing point at .0

Dry ice is a solid form of carbon dioxide that produces a cold dense mist. I first learned what Dry Ice was in fifth grade, this was due to the fact that my class had taken a field trip to River Legacy Park. Where we saw an experiment and learned facts about dry ice. This led to a fascination with dry ice, in this experiment I will test whether the temperature of water and soda affect when poured over Dry ice. Dry Ice has multiple purposes some of which, is chemotherapy, to carbonate liquids, store food, and accelerate plant growth. Since, I always liked the thought of working with Dry Ice I had begun to think of an experiment to do for the IA involving Dry Ice. After much consideration I choose to test how soda and water would

The procedures followed was to rinse five ice cubes in cold water and put them all together so they are close and touching, more so that they could freeze into a clump. I had to do the same with a group of 4, 3, and 2 ice cubes. And put aside a single ice cube on a fifth plate. Then fill the glass 3-1/4 full with soda. Then I had to stand around and wait until the fizz die

During my experiment I 've learned a fairly great deal about temperatures, and how to convert Celsius, Fahrenheit, and Kelvin. In my observation I have learned that water boils at 100 degree Celsius, and freezes at 0 degree Celsius.

In 1932, twelve railroad cars were properly insulated to handle dry ice in a successful test. Unfortunately, during this test there were eight cars built with mechanical refrigeration that proved to be more affective than the early dry ice cars. They found the dry ice to be more affective in the transport of ice cream. With a temperature of -114deg F, Breyers Ice Cream in 1927 found dry

Anna’s typical workday would last from 3:00 P.M. to 6:00 A.M. As part of her observation preparation, she would visit with the observatory staff to discuss new findings and review what has taken place since her last visit. She stars by pulling out a list of dwarf galaxy stars, ordered by priority. She chooses the first star and asks the operator to move the telescope into position so that she can begin collecting starlight data. The article states that her research primary focuses on stars in ultrafaint dwarf galaxies. This article goes onto discuss that after the big bang, the first stars were formed from gaseous clouds. We know the big bang to be when the universe

He spat again, in the air, before it could fall to the snow the spittle crackled. He knew at fifty below spittle crackled on the snow, but this spittle had crackled in the air. Undoubtedly it was colder than fifty below--how much colder he did not know."

The incorrect chemistry is that Olaf was in the water. This is incorrect because ice cannot be placed in warm water because it will acquire heat and turn from solid state to a liquid state. The heat is always transmitted from the hot body to the cold body. The hot body loses heat and the cold body acquires heat. Ice melts at 32 degrees Fahrenheit (0 degrees Celsius) During the transformation process, the temperature remains constant at 32 degrees Fahrenheit (0 degrees Celsius) until all ice is turned into water.

A bubble is a thin liquid enclosure of air or gas. (5) It is a big ball of air surrounded by a thin layer of liquid. Traditional bubbles have a spherical shape. (4) “The round shape of a bubble is due to the competing forces of the air within, and the liquid surface of the bubble, which prefers the least amount of surface area. A sphere is the shape with the least amount of surface area for the volume within. So, when air or gas is forced inside of a liquid shell, a sphere is naturally formed.”(1)

The first step needed to carry out the experiment, was to crush the dry ice into smaller pieces in order to fit into

In late 2001, an amateur astronomer happened upon an uncharacteristically bright object in the Monocerotis constellation (Figure 1). Over the next several months the object went through periods of intense brightness the likes of which had rarely been seen before. My research this summer was to use a computer simulation to better understand what may have caused this strange event known as V838 Mon. In order to understand what may have caused the bright outbursts, it is necessary to try and make a model of the event that caused them. To make this model, we implement a Smoothed Particle Hydrodynamics (SPH) code called Starsmasher. The code calculates the movements of many small particles to replicate the movement of a fluid, such as a liquid or

While the solution boiled, 2-3 ml of water was added to the solution. After the solution was boiled, gravity filtration was in action and allowed the solution to drip. After the solution was separated, the solution was removed from heat and cooled to room temperature. The room temperature solution was then placed in an ice bath for five minutes to cool further. The cooled solution formed crystals on the bottom which looked like snow.

Most people in their lives have seen a shooting star and exclaimed, “Make a Wish!” However, this so called “shooting star” is actually the clue to how the solar system was created. While this rock object is in space it is called a meteoroid, and then it is called a meteor when it enters a planetary atmosphere. The friction of the meteoroid created by the incoming velocity causes it to heat up quickly, and in result a bright flash of light. As noted above, this is what people see when watching the sky. In addition, meteorites gave the first knowledge about abundances of chemical elements in the solar system in the 1930s through 1950s. Meteorites are the most ancient rocks known to mankind and have helped pave the way in the study of the formation

After 5 min passed the plastic container created a thin layer of ice surrounding the container.

With even more weight, these lower layers of ice began to flow and move were slowly.
