PHYSICS INTERNAL ASSESSMENT By: Salman Charolia For the coffee filter paper, how does the mass, by adding items such as paper clip, affect the time for the coffee filter to fall from an initial height? Design: Problem: For the coffee filter paper, how does the mass, by adding items such as paper clip, affect the time for the coffee filter to fall from an initial height? Hypothesis: If the mass is increased then the time for the filter paper to fall will decrease because there is more force occurring

This is not detrimental to the understanding the resuspension characteristics of the sample, or being able to use that data for stress plots. However, it would be preferable to have stresses below observable
beaker, stirring rod, goggles, scale, filter funnel, filter paper, evaporation dish. The variable that I will be changing is the mass of Iron Filings (in grams) added to the Copper Sulphate. Plan: 1. Collect all appropriate apparatus and then set up. 2. Carefully pour 20cm³ of Copper Sulphate into a beaker. 3. Place a sheet of filter paper on to the scales and then set scales to zero. 4. Measure out 0.5g of Iron Filings on to the filter paper by reading the scales. 5. Pour the
solution through a hot filtration apparatus (filter). -Formation (Recrystallization) – allows the hot solution to cool and begin to form crystals. For rapid cooling, an ice water bath can be used. -Isolation – Using a vacuum filtration, the excess solvent will be removed from the crystals. -Drying the crystals – the crystals will be transferred from the Buchner or Hirsch funnel in vacuum filtration to a watch glass. Cover the watch glass with a filter paper to protect from airborne contaminants. Drying

After results, it was concluded that isopods prefer normal temperature conditions over warm conditions. We created these environments by adding water onto filter papers with the accounted for temperature measurements. The reason for the results could be seen in a usual isopod environment, it is usually dark, fresh, and moist, and the normal water temperature being the closest to that was the reason for their choosing
Aim To produce a pure sample of Barium Sulphate (BaSO4) of at least 0.50 grams. 4. Apparatus & Materials Chemicals used: Barium Nitrate, Ba(NO3)2 Sulphuric Acid, H2SO4 Lab equipment used: Glass beakers (2) Funnel (1) Filter paper (5) Conical flask (1) 5. Method 1. Collect 50 cm3 of Sulphuric Acid and 50 cm3 of Barium Nitrate in separate beakers. 2. Add the Barium Nitrate to the Sulphuric Acid [Time taken for steps 1 and 2: 1 minute] 3. Stir the resultant
ice-water bath from 4:00 until 4:20. As we waited I began to set up our filtration system. I used a ring stand, right angel clamp, three finger clamp, Buchner funner, filtering flask,rubber tubing, and filter paper in the Buchner funnel. I turned on the aspirator and pored some water over the filtering paper in order to create a good
when we looked at the chromatograph paper after “filtering it” we saw the blue, yellow, and pink pigments that made up the green/black liquid. We started out by pouring the black ink into a filter and the substances were not separated. Because filtering the black liquid didn’t separate the substance, we then used chromatography paper to separate the ink. Chromatography paper is a method used to separate colored substances. We put a small line of black ink on the paper then put the tip in the water and
The materials are two 50 milliliter beaker, a funnel, a ring stand, two 400 milliliter beaker, filter paper, clay triangle, and a mortar and pestle. The next thing is you must weigh a piece of paper or a weigh boat whichever you are going to put the cereal on. Once we have done that we must weigh 0.8 grams of fruit loops and record the weight. Afterwards you must crush the cereal using a mortar
filtration is that decanting is the process where you would pour the liquid out of the container to leave the solid behind. . Filtration is where you would use a medium or a filter paper to separate the solid and liquid. What chemicals (substances) are in the filtrate?hOw do you know by your observations? The substances in the filtrate are distilled water and salt. Based on my

Since Google Analytics offers numerous data, one needs to determine which tools they are going to use based on the company’s goals and marketing strategies. This paper will discuss the tools to use for small business

Voyeurism, titillation, narcissism÷all in a rebirth of classical American literature, which through their filters becomes sappy love stories with politically correct happy endings. In this way, their gifts are made more palatable for an audience they feel is not quite ready for films dealing with bitter social controversy, such as sin, hypocrisy, spiritual crisis
in water treatment, paper making, and mineral processing.[8] Filtration is used to recover solids, to clarify liquids, or to recover both phases. The filtration apparatus in the Uni-Minn Development Cooperation’s Unit Operations Laboratory is a vertical pressure leaf filter. Specific details of the apparatus are contained in the apparatus subsection, but a basic schematic is shown in Figure 1.1 below. A vacuum is utilized to force flow of a slurry solution through a filter medium of cross-sectional
predators who may try to take advantage of them. In addition they may be exposed to obscene materials. Schools have installed filters, but they sometimes are unable to prevent all inappropriate material from being viewed. Many teachers complain that the internet allows plagiarism and all out cheating with access to pre-made term and research papers (where do you think this paper came from). Many critics of the educational system also point out that often students only like to use computers to access
Pets are very cute, but lots of people give up them because of pets allergy, which makes me heart-break. In fact,there are many precautions you can take. Air purifier with HEPA filter is your top choice, because the pets allergens mainly come from the dander of pets. Different air purifier is designed to clean different pollutants, and it is important to find out what air pollutants you want to remove before purchasing the air purifier. Pet allergy Normally it is not the pet hair that causes allergy
All those times that I hit you. I am sorry. I am a monster. I guess I do deserve to die like this. Last month I didn't even know where the hell Zaire was. All I knew was that it was some poor backwards nation in Africa that we sold water filters to. Funny how things turn out, I am going to die in this god forsaken place. Twenty people in this village have died. The rest that haven't probably wish they were. David is already dead. Honey, you remember David right? That junior assistant
active member of it. Although his narrators are not his normal voice, they are still a part of his writing self. They still must go through the filter of his conscious thought to be allowed to write the story. This means that when the reader is engaged in the process of comprehending this story, they unnoticeably bring together three separate filters. The author's, the narrators', and their own. This voice creates a story within a story. They describe the lives of a suburban group of
mysteriously, on a path between town and Bly. He died from a blow on the head, supposedly from falling upon a rock in the road. The reader's only impression of the death is through Mrs. Grose's story, though, and so, Solomon hypothesizes, she filters the information to make it seem less extraordinary a demise. Perhaps Mrs. Grose killed him out of jealously. The reader can infer from this point of view that Mrs. Grose somehow also had a hand in Ms. Jessel's death. Mrs. Grose then proceeds
Time - Temperature (of water) - Filter Planning (b) Apparatus/ Materials - Round bottomed flask under reflux - benzylalcohol - HCl - Na2O4 - Büchner funnel - beakers - sodium carbonate Procedure The benzioc acid is synthesized by heating benzylalcohol in a round bottomed flask under reflux. In addition to that, we use Na2O4 as a oxidizing agent. After that, we use HCl to precipitate it. After the some time, we filter it through a Büchner funnel before it
