Pressure vs. Volume Ib Chemistry Sl Full Lab Write- Up Essay

A sample of gas at 6.0 atm and 5.0ºC increases in temperature to 35ºC. If the volume is unchanged, what is the new pressure?

B. How does this graph illustrate Boyle’s law? As more pressure is added the volume decreases and the graph shows this because it is decreasing as well. _________________________________

Think about the gas laws we are studying. Boyle’s law tells us that pressure and volume are inversely proportional. Charles’ law states that volume and temperature are directly proportional. We also know that pressure and temperature are directly proportional. Discuss at least one instance in your personal experience where you have seen one or more of these laws in action.

In order to use the Ideal Gas Law equation, the atmospheric pressure of the room must be recorded from the barometer which was 0.9826 atm. The actual and theoretical yields can be calculated using the Idea Gas Law equation and the percent yield can then be determined. Finally,

The pressure of a gas sample increases for a decrease in volume and decreases for an increase in volume.

The density decreases. Density of the liquid sample is the mass divide by the volume. If the mass stays constant and the volume increases then the density of the liquid sample will decrease.

As a result, it is a common practice to measure the volume of a gas by collecting said gas at the top of a container filled with water, with its opening facing downward in another container of water. This process is called collection of gas over water. The volume calculated from this practice may be used — in conjunction with two other factors (Pressure, Moles, or Temperature) — to determine another characteristic of a gas. This is able to occur due to the principles of the Ideal Gas Law. The Ideal Gas Law, PV=nRT, is derived from Boyle's Law, Charles Law, Avogadro's Law, and Gay-Lussac's Law,.

The main purpose of this lab was to study the capillary pressure (Pc) in eight sandstone core samples in order to obtain saturation values and the height above the free water contact in the reservoir rocks. In general, capillary pressure can be defined as the difference in pressure between two immiscible fluid phases (usually oil and water) that occupy the same pores. It is basically generated by the interfacial tension between two different phases. It is considered to be one of the important factors that control fluid distribution in reservoir rocks. Moreover, capillary pressure can be the key to determine the relationship between important rock properties such as porosity, permeability, and water saturation above oil-water contact in reservoirs.

Robert Boyle, a philosopher and theologian, studied the properties of gases in the 17th century. He noticed that gases behave similarly to springs; when compressed or expanded, they tend to ‘spring’ back to their original volume. He published his findings in 1662 in a monograph entitled The Spring of the Air and Its Effects. You will make observations similar to those of Robert Boyle and learn about the relationship between the pressure and volume of an ideal gas.

If you have never heard of duct pressure testing, you’re not alone. Many homeowners are unaware of this practice and the important role it serves in keeping your air ducts functional. This is a diagnostic procedure to measure the air tightness of the air ducts in your home. It can be done in a home that is already inhabited, as well as in a newly built structure. If you are unsure as to whether the ducts in your home should be pressure tested, consult TI Dawson Heating & AC. We provide duct pressure testing to residents in the Martinsburg, WV area.

Where Boyle's law states that pressure is inversely proportional to volume under a constant temperature and a fixed amount of gas; where Charles' law states the volume and absolute pressure are proportional under a constant pressure, and Avogadro's law which states that volume is proportional to the amount of gas present under constant temperature conditions (LeTran, 2013). The Ideal Gas Law can be written in a few ways, however, the way it will be analyzed under the scenario explained in this paper can be seen in equation 1. In this equation P represent the pressure of the gas, V represents the volume of the gas, n represents the amount of gas in moles, R is the ideal gas constant and T is the absolute temperature of the gas ("Ideal Gas Law," 2018). All of the terms are pretty self-explanatory except for the gas constant and the absolute temperature of the gas. The ideal gas constant is the amount of energy per mole of the gas, which is equivalent to Boltzmann's constant, however it is expressed per particle (Gas Constant," 2017). R is the same value whenever evaluating an Ideal Gas Law equation, however it varies based on the units of measure used. The absolute temperature is the average kinetic energy that makes up an object. Therefore, an object cannot have negative energy and the absolute temperature can never be less than zero. This is why temperature is

Neyra and I, under the influence of scientific curiosity, did the Boyle’s Law: Apparatus Lab to relate our results to the law. The lab places Boyle’s law into action to see if the lab results match up with the law. We hypothesized that the results of the experiment would correspond to the relation between volume and pressure established by Boyle. We began by setting up the cylinder apparatus by inserting the plunger into the cylinder and covering the plunger with a plunger platform. Once the apparatus was set, we began placing weights (pressure) and recording the volume in ml. To get a more accurate conclusion, we repeated the process four times. In fact, one trial consisted of adding consecutive number of weights (until four), and then removing them until there were zero weights left. Once we had our data recorded, we used the average of all trials to do calculations. After reading our data, we concluded that our hypothesize was very true to conclusions drawn by Boyle’s apparatus experiment. When there were more weights, the volume seemed to be smaller. However, once we started removing weights, the volume began to

Saturation vapor pressure is a unique function of temperature as given in Table 5.6. Each temperature in the table may be interpreted as a dew point temperature, because as the ground cools, dew will begin to form at the temperature corresponding to the vapor pressure.

I possess the skill to work under pressure. By that, I don’t mean to procrastinate on my responsibilities just because I can handle the situation well. Due to the nature of my job, I developed this skill and I still apply it on a regular basis. To be honest with you, I’m not planning to use it on my assignments because I think that will be an indication of not managing my time well. As far as attributes, I think that my perseverance has allowed me to get here. Because of the fact that English isn’t my first language, I couldn’t imagine enrolling in a graduate school since I immigrate to this country after 14 years

Charles’s Law describes that temperature and volume are directly proportional. Therefore, when temperature increases, volume increases and the same for the opposite, when the temperature decreases, the volume decreases as well. The mathematical way to display Charles’s Law is where the V represents the volume of the gas, the T represents the temperature of the gas , and b represents the pressure of the gas.
