Liquid oxygen

Crystals form when a type of liquid cools down, and then hardens. The process when crystals grow is called "nucleation". Whenever a person eats salt, they are eating salt crystals. These crystals are called salt crystals. To make homemade salt crystals, the materials you need are hot water and salt. When dissolving salt in water, the salt is not changing its properties. This project will use different types of waters to see how many more crystals it will help grow. Dasani water is a brand of water made by The Coco-Cola Company. The Coco-Cola Company came out with this water in 1999. In order to create Dasani water, the Coco-Cola Company starts with the local water supply. Then, it gets filtered for purity. In order to be filtered for purity,…

start off with evaporation. Well, what really is evaporation? Most people just know evaporation as the change of state from a liquid to a gas. Yes, it is that but it is also the most common way to put these liquids back into our atmosphere. Another thing is a lot of people think there is no point to evaporation…

is the story that lies at the very center of the Nazi-UFO myth, the idea that the Nazis had a field-propulsion flying saucers. The Bell's a propulsion system, kind of a reactor which is the power source. The ground leader's name was Jakob oSporrenberg who was sentenced by a Polish War Crimes Court after the war for the crime of having murdered 60 Germans that were part of this project, in order to keep it secret. In his affidavit before the Polish War Crimes Court, he describes details of this…

control variables, which are variables that scientists want to be kept constant in our experiment. They do have a pretty big effect in our experiment because we choose to leave these variables constant in order to make sure our data is accurate, but they are not the main focus of our experiments. The control variables for this test are the size of the can which is 355 mL, the time we wait until we flip the can into the pie tin which is one minute, and the amount of liquid in each can which is 10…

statement is true? A Only sample B is solid. B All four samples are liquid. C Only samples A and C are liquid. D None of these ____ 15. Hailey is investigating changes in the states of matter. Wearing safety gloves and goggles, she is heating a pan of water on a hot plate. She observes water vapor beginning to rise from the surface of the water. As the water reaches 95°C, what can Hailey expect to observe soon? A Drops of water dripping down the outside of the pan B Bubbles of gas forming in…

One of the most unusual substances in chemistry, slime blurs the line between solid and liquid stages of matter. Slime and other substances like it are common in the average everyday life today, and yet are almost unnoticed. Slime is a colloid, a substance that shares both liquid and solid traits. Many colloids are polymers, which are a certain type of molecule. Although slime may seem simple, in reality it is quite complex in the microscopic standpoint. Slime can also be referred to as a…

Lab Report: Density and Viscosity Problem: What is the effect of density on the viscosity of a substance? Hypothesis: Density will affect the viscosity of a liquid. The order of the liquids from most dense to least dense is: syrup, detergent, water, oil Background: Density and viscosity are closey related in which they both affect one and other. Denisty has many factors like weight, mass, and volume. To work cohesivly there are different things we must pay attention to. Density is how closley…

AIM OF THE PRACTICAL The aim of this practical was to investigate the reality or the accuracy of the formula for the resultant force on and the position of the centre of pressure on a vertical rectangular surface. SKETCH OF APPARATUS Counterbalance weight Balance pan(with 20g mass piece) Flat/curved surface(as shown below) Water Beaker Mass pieces(20g each) SUMMARY OF THEORY Hydrostatic force is the force exerted by the…

3.1.3 Pump A pump is a gadget that moves liquids (fluids or gasses), or once in a while slurries, by mechanical activity. Pumps can be characterized into three noteworthy gatherings as indicated by the technique they use to move the liquid: direct lift, dislodging, and gravity pumps. Pumps work by some component (regularly responding or turning), and expend vitality to perform mechanical work by moving the liquid. Pumps work by means of numerous vitality sources, including manual…

provides the thermal energy for the thermal decomposition and subsequent recombination of the constituent species followed by sintering and recrystallization of the clusters of crystallites results in coherent film. The chemical solution is atomized into a spray of fine droplets with the help of carrier gas. As compared to other film deposition techniques, pyrolytic deposition of thin films is relatively inexpensive in terms of equipment cost. In a properly designed reactor and after suitable…
