Combined Gas Law Lab

A phase of matter is a uniform with respect to both its physical and chemical properties. Matter undergoes phase transitions that change from one phase to another. A state of matter is a form that matter can take such as solids, liquids, gases, and even plasmas. There are some other states of matter that appear under extreme conditions but these are the main ones you use in your everyday lives. For example, imagine you have gatorade and water.

In “This Way to The Gas, Ladies and Gentleman” by Tadeusz Borowski was a poet and was detained because he was clinically depressed. In this essay I will discuss the importance of “human nature” in the Holocaust and why it contributed to the deaths of millions of Jewish people (among other minority group’s i.e. gay men, black people, disabled people). The question of human nature is irrelevant and inappropriate in discussions about the holocaust. Since it was those questions of human nature that - What makes a human? What is natural?

If an object is less dense than the water or air surrounding it, the object floats; if the object is denser, it sinks. When an object does float on water, the water will not remain flat, but will instead form a bump or dimple, depending on the object’s weight. When two identical objects float close together, the change is more noticeable—two cheerios, for example, will cause slight dents in the milk and close together, will appear to “fall into” each other or form clumps. Surface tension is a property that makes the surface of a liquid act like a flexible membrane. It results from various

When the volume was 5.8 ml the pressure was 192.52 kPa but when the volume double (10.8 ml), the pressure was 133.38 kPa. 2. If the volume is halved from 20.0 mL to 10.0 mL, what does your data show happens to the pressure? Show the pressure values in your answer.

On January 18, 2015, the New England Patriots and the Indianapolis Colts played in the AFC Championship game in a chilly temperature of 51°F. The Patriots were accused of cheating when, at half time, 11 of their 12 game balls were found to be two pounds psi less than the regulation size of 12.5 to 13.5 psi. Although the balls are gauged 2 hours and 15 minutes prior to the game, they are returned to the teams before the game started. Based on extensive research and data, the Patriots’ balls were tampered with prior to the game. Objects with gaseous interiors have a tendency to decrease in pressure when exposed to cold temperatures but the decrease will only be minor.

In the poem “Treblinka Gas Chamber”, by Phyllis Webb and in the TRC’s “The History”, both texts share a common theme of inhumane treatment towards children within certain cultural and ethnical groups. While the two authors explore distinct historical contexts, both texts are centred on racial segregation with nationalistic motives. Phyllis Webb appeals to a logos strategy through the use of allusion. In her poem, “Treblinka Gas Chamber”, Webb presents fictional and historical examples to display her knowledge and establish her credibility.

The gummy bear's mass and volume will increase while the density of the gummy bear would decrease after it is put into water overnight. (#)This lab experimented to figure out wah changes would take to the gummy bear’s mass, volume, and density after sitting in a cup of water overnight. To do this the gummy bear's dimensions and weight was taken on the first day, along with its density and then the gummy bear was placed and water. When the gummy bear was taken out of the water on day two, the dimensions, weight, and density were taken again, and the difference between the two days was found. (#1)

Conclusion: The objective of this lab was to determine the velocity of an object moving down an incline by applying the Law of Conservation of Energy. This velocity would then be compared to the experimental velocities to calculate the percent error. This objective was accomplished by releasing a dynamics cart on a dynamics track with different initial and final heights. The height of the ramp was changed by using textbooks to prop up one end of the ramp.

Stoichiometry is a method used in chemistry that involves using relationships between reactants and products in a chemical reaction, to determine a desired quantitative data. The purpose of the lab was to devise a method to determine the percent composition of NaHCO3 in an unknown mixture of compounds NaHCO3 and Na2CO. Heating the mixture of these two compounds will cause a decomposition reaction. Solid NaHCO3 chemically decomposes into gaseous carbon dioxide and water, via the following reaction: 2NaHCO3(s) Na2CO3(s) + H2O(g) + CO2(g). The decomposition reaction was performed in a crucible and heated with a Bunsen burner.

VARIABLES: There are independent variables, dependent variables, and controls. the one that is being tested and the one that is the inconsistent variable in the Independent variable like the volume and surface area of the agar cubes. The variable that is kept consistent is the dependent variable such as the percentage of diffusion of pigment in the agar cubes. The constant variable is the features of the experiment that is kept the same throughout the entire experiment such as, the amount of time the agar cubes are left in the beaker and the amount of acid in the beaker.

II. Introduction: For this lab, students are getting knowledge and understanding of how many types of energy work while throwing an object from high position to the lower position. It also depends on a certain level, energy will changes while throwing an object up and down. Students will also learn about the principle of the physics, which are the law of conservation of energy.

Place the the beaker onto a hot plate that is on a low heat setting (about setting 3). Every 5 minutes for 20 minutes, measure the circumference of the balloon and record it in Data Table A. You can measure the circumference of the balloon by looping a piece of string around it then using a ruler to measure the string’s length. Record the data in the data

The law describes that when the pressure of a gas remains the same/constant, the volume of the gas is directly proportional to the temperature. This means that when the volume increases, the temperature increases, and oppositely the same would happen if the the volume had decreased. In the experiment, the law supports my results because when the volume increased, so did the temperature.

The movement of gas through the larynx, pharynx and mouth allows humans to speak, or phonate. Vocalization, or singing, in birds occurs via the syrinx, an organ located at the base of the trachea. The vibration of air flowing across the larynx, in humans, and the syrinx, in birds, results in sound. Because of this, gas movement is extremely vital for communication purposes. Temperature control

The purpose of this lab was to determine the molar volume of Hydrogen gas and compare it with the value predicted by the Ideal Gas Law. In this lab, I was able to calculate the number of moles of H2 produced and measure the volume of H2 gas produced and also notice how the volume, temperature and pressure changed when it had a reaction with different amounts of Zinc. In the first experiment, I determined the change of temperature, pressure and volume in Hydrogen differing from its initial temperature, pressure and volume. After adding 0.250 g of Zinc to the first part and 0.500 g of Zinc to the second part experiment to Hydrogen gas and using the Ideal Gas Law, I could notice an increase of pressure and temperature in the experiment while
