The Air And Gravity Prezi German Analysis

Coehsive forces between water molecules are responsible for surface tension. This makes it harder to move through a surface. Surface tension also forms water

Aquatic organisms use oxygen just like terrestrial organisms. The oxygen percentage of the atmosphere is approximately 20%. The oxygen percentage of water is much lower, at 1%. Many factors affect how oxygen and other gases dissolve in water. The purpose of the experiment was to discover if temperature is a factor for gases dissolving in water. In a beaker, 225mL of water was filled at varying temperatures between 0 degrees Celsius and 65 degrees Celsius. Three 12cc capacity syringes were filled with 7cc of Diet Mountain Dew, the syringes were then pointed upward, pressed of excess carbon dioxide leaving 5cc of seltzer, capped, and plunged into the water. A stopwatch was then used to time for three minutes, after which the syringes were removed

The method of designing an environment inside of the tube to induce CO2 to turn into a liquid is elegant and effective. In all tubes, liquid was visible shortly into the placement of the tube in the water bath, and that same liquid was visibly boiling later into the experiment, which was expected. However, only 2 of the tubes being observed by the entire lab seemed to show a very faint amount of oil, however, it seemed that the sample could still be used for the gas chromatography/ mass spectroscopy step that was supposed to follow. However, that sample was rendered unusable after the

Next. the aluminum foil and the rubber band were taken off of the Erlenmeyer flask. 2 mL of the unknown liquid was poured into the flask. The aluminum foil was placed back on the mouth of the Erlenmeyer flask and loosely folded around its neck to make an aluminum foil cap. The rubber band was used to tightly secure the foil cap in place. Using

Molecular sieves adsorb the highest amount of water, produce the lowest water dew points and sweeten (remove hydrogen sulfide) and dry the natural gas.

9. The little man was dragged inwards 1nm, waiting for the temperature to get back to 300 K. The volume and pressure readings were recorded. 10. Readings were continually taken as done in (9), the volume and pressure was recorded each time.

There and the forces attracting that bound liquid to another surface are better than the forces of gravity.There’s many chemical reactions that take place through the lives of plants. Every

In this lab, we see the effects pressure and temperature can have on a soda can. The real question is what's happening inside on a molecular level. Placing the can on hot plate means the temperature of the water is increasing. This water is beginning to boil, or sufficient kinetic energy is occurring throughout the entire liquid. This boiling then creates water vapor where all the gas particles are rapidly bouncing off the can, and because it has a hole the water vapor is escaping through it and the pressure is the same inside and outside the can right now. Fast forward to right before dumping it in the ice bath, the steam can no longer escape, pressure is building up and the particles are moving fast, but because it was taken off the heat

In the experiment of crushing the can through a series of actions taken, we’re left to watch it crush in action. So how exactly does it all happen from the start to finish? During the very start of it, the can and air around it was room temperature and so was the water in a container nearby. The boiling station were turned on and a soda can filled to about 20 mL of water, after a long while, it would begin to boil up when placed on those stations. The water particles have moved rapidly and split apart into vapor as the particles outside began to move faster than usual. The particles movement of the water made it into water vapor, filling up the can with water vapor. This replacement leaves no room for air to be in there and thus, the can

Evaporation lowers the temperature of the glass head (heat of vaporization). The temperature decrease causes some of the dichloromethane vapor in the head to condense. The lower temperature and condensation together cause the pressure to drop in the head (by the ideal gas law). The higher vapor pressure in the warmer base pushes the liquid up the neck. As the liquid rises, the bird becomes top heavy and tips over. When the bird tips over, the bottom end of the neck tube rises above the surface of the liquid. A bubble of warm vapor rises up the tube through this gap, displacing liquid as it goes. Liquid flows back to the bottom bulb (the toy is designed so that when it has tipped over the neck's tilt allows this), and pressure equalizes between the top and bottom bulbs. The weight of the liquid in the bottom bulb restores the bird to its vertical position. The liquid in the bottom bulb is heated by ambient air, which is at a temperature slightly higher than the temperature of the bird's

This lab is to properly demonstrate how to find the Ideal Gas Constant, R, by using the ideal gas law, PV=nRt. In this equation, P is the gas pressure in the atmosphere, V is the gas volume (L), n is the number of moles in the gas, T is the gas temperature (K), and R is the gas constant. This ideal gas law helps determine the state of a gas at a certain amount, volume, temperature, and pressure. The hydrogen is collected by displacing water, which is submerging an object completely in water (gas buret) and recording how much the water rises. The volume of the water that is displaced can be measured and from this, the volume of the submerged object can be calculated. The hydrogen gas that is collected will also be mixed with water vapor, therefore

When a vacuole is filling with water, it will make the plant cell rigid and hard. I learned that even if the plant cell is not in the ground it can still become turgid or flaccid. I learned how to use a squeezer to put vanilla in a balloon. When I put the vanilla in the balloon, I did not accept the smell to leak outside of the bag. After an hour I was surprised that the bag smelled like vanilla. I learned the smell was in the bag because it used passive transport to get through the balloon. Passive transport is when something is transported without using energy. The smell wanted to leave and get to the outside of the balloon. When I left the bag open for two minutes, the smell was not concentrated. I learned that the smell then transported to the outside of the bag using passive transport. I learned the difference between diffusion and osmosis. Diffusion is the movement of molecules from an area of high concentration to an area of low concentration. Osmosis is the diffusion of water across a cell membrane. In conclusion, I learned that science can show you how many things work and how you can be surprised of what you

The pressure in the test tube had heightened considerably due to liberation of chlorine from the solid compound and this pressure was enough to result in liquefaction. Using the same procedure, Faraday was also able to reduce other "permanent" gases such as sulphurreted hydrogen, nitrous oxide and ammonia to liquid state (Faraday, 12-18). He thus showed that the distinction that had hitherto been drawn between vapors and gases was fallacious and that permanent gases were merely vapors of liquids that had low boiling points (Crowther, 22-23). His research won acclaim in scientific circles and people as famous as Andre-Marie Ampere (James, 328). Faraday indicated in a letter to the French scientist Charles-Gaspard De La Rive on March 24th, 1823 that

9) 10 mL of sugar was added to the solution and the balloon was quickly placed over the opening of the bottle to minimize the loss of any gas from the system.

I want to start by recognizing that in my earlier film papers I have made the mistake of summarizing all of the science in each of the films from start to finish. By doing so my paper essentially became a summary of the film rather than an explanation of the science found within it. To avoid repeating these mistakes I would like to focus on a few scientific concepts that I found interesting in this film, Gravity. The first, and likely most obvious is the concept of surviving in space. Second, the concept of floating freely in space. Third, the concept of decomposition in the zero-gravity atmosphere of space. And fourth, the part of the movie where lieutenant Kowalski propels himself with a fire extinguisher. I believe that Isaac Newton’s three laws can help me to explain these concepts. Gravity was a thrilling film that showed a situation in which astronauts were stranded in space without a spacecraft or any means of communication. The surviving astronauts had to fight for their lives in theoretically hardly survivable and unlivable conditions.
