Barrier Review Paper Essay on Barrier Pavel Vezhinov Barrier » From the distant fairy tales of childhood is the absolute perception of love at first sight, movement, touch. And I am sure that love is so deep, and I understand that there is nothing to add to the entire future life But in real life it is not so Love -. Only the first song in a long or a short melody for men and women In the 18 years I took the story as a beautiful (albeit tragic) tale about love. At 31, I re-read it as a banal story about a misunderstanding of men and women We will write a custom essay sample on Barrier Review specifically for you for only $16.38 $13.9/page Order now We will write a custom essay sample on Barrier Review specifically for you FOR ONLY $16.38 $13.9/page Hire Writer We will write a custom essay sample on Barrier Review specifically for you FOR ONLY $16.38 $13.9/page Hire Writer Mathematical musician Antonio -. Creative expression logical masculinity. Crazy Flying soul Dorothea irrational, empathic, emotional embodiment of the female There is no sense to retell the story -. Archaic fear of how the world of men to change themselves, their way of life, knowledge and values. Alas -. Change the feat just available Every betrayal someones death. Antonio gave no Dorothea, and especially yourself. Betrayed at the moment when it is not the case, and what has happened, has its reasons and of course the consequences of (a pity that they are almost not shown him has depended on another persons life. In the story would be in story). Sadly confrontation of people created in the name of and for each other. How to survive in this war? How to reach an understanding, harmony and unconditional lived happily ever after? How many times have ignited the lovers to each other we have to become more attentive, kinder, chutche, openness? Talk to me instead of to kill me! Permit me to solve the most, rather than to decide for me! Hold me instead szyvat their shelves against me! Let love into your life! Not hearing these prayers, we do not only kill the other, we will execute the best part of himself. And he knows there will be a revival of

Density Lab Report Essay Example

Density Lab Report Essay Example Density Lab Report Paper Density Lab Report Paper Density is defined by its mass per unit volume, and is most often written in mathematical terms as; Mass is usually given in grams, g, and volume is given in cubic centimeters, g/ com, or, grams per millimeter, g/ml_ Density is not a property that depends upon the amount of substance present. For example, one gram of lead and one ton of lead have the same density. Density also does depend on temperature. For instance cold water is denser than warm water; ice is less dense than both. The method used for determining the density Of a substance depends on the nature f the substance. In this lab the densities of unknown irregularly shaped solids and liquids was determined. Accuracy and precision of the results will be estimated, and attention Will be paid to the correct use of the significant figures. The experiment approach that will be used will tell the mass and volume of the metal and liquid determined by measuring these two quantities with a graduated cylinder and Beirut. Procedure: a) The density of metals First obtained a quantity to unknown metal. Recording the unknown number, I used only one type of metal for this part of the experiment. The unknown metal that was instructed to use was a chunk, therefore, used a Some graduated cylinder, When using the Scam cylinder, I filled it with water to approximately the ml mark. Then recorded the exact volume of water that was added. Placed the cylinder and water on the balance and recorded the mass to every 0. Lag. Added the metal to the graduated cylinder until the water level increased by approximately 2_Mom_ Being sure to tap the sides of the cylinder to release any air bubbles. I then recorded the volume of the water plus teal to the nearest 0. ml Then recorded the total mass of the cylinder, water and metal. Added more pieces of metal to the cylinder until the water level had increased by 2. Mi. Then recorded the exact volume Of water plus metal and total mass of cylinder, water and metal. Repeated the procedure twice more. Being careful not to go over the Mimi mark. And recording the data each time. Calculations: determined the total volume of metal in the cylinder by su btracting the volume of water from the volume of water plus metal. Then found the corresponding ass of metal by subtracting the mass of the cylinder and water from the mass of the cylinder, water and metal, I plotted out the graph showing the total mass of metal on they-axis, and the volume on the x-axis. I found the slope of the line by taking two random points from the graph, performing the slope formula and finding the density. From the table provided, I identified the unknown metal to be silver, b). Determining the density off water/ethanol mixture. Obtained an unknown solution from the instructor. Then recorded the number of the solution. Then rinsed a burette with a little of the ethanol solution, and filled the burette with that same solution. Read the burette level to the nearest 0. Ml. Then weighed an empty Mimi Erlenmeyer flask. Turned the knob Of the burette and put approximately 23. Ml of solution into the flask. I read the burette again, to O_Osmosis and recorded. Next weighed the flask and its contents, by placing the flask on the balance and recording the temperature Of the solution. I then determined the density Of the solution by taking the mass of solution and dividing by the volume of solution. Repeating the procedure twice more using a clean flask and the same balance each time. Calculations: For each of the three trials calculated the density of the solution and determined the mean, average deviation from the mean, percent precision and the range. Then drew a calibration curve from the data given on page 17 of my Laboratory Manual, Discussion: Based on the value of my density, and based on the literature values given on page 16 of my Laboratory Manual, the unknown metal is silver. The density I had obtained trot the slope of the graph was 9. Egg/ml. En compared my density to the chart given, looking for a similar density, The density of my unknown metal was not exact with a particular metal given in the chart, but kept in mind that the density of silver can vary depending of the state it is in, Error Analysis: The possible sources of error in finding the density of the unknown metal and liquid would have to be my consistency throughout the experiment had approximated with my bare eye and was not consistently exact. Therefore, there was an inaccuracy in reading the volume displaced from the graduated cylinder and the Beirut.
