Boyles Law Apparatus
Abstract The objective of this lab was to determine the relationship (if any), between the pressure and volume of a gas given the temperature and # of molecules remained constant. Using the Boyle's law apparatus, and textbooks to demonstrate pressure it was concluded that there was a relationship between pressure and volume. However, the relationship was not a direct relationship, and it was determined that the pressure and volume of a gas are inversely proportioned. Thus,proving Boyle's theory correct. Introduction

Objectives: The main objective of this lab was to determine the relationship between the volume and pressure when the temperature and number of molecules remains the same throughout. Other minor objectives of this lab were to determine any possible source of error, so there is more awareness of these errors when conducting another experiment.

Theory: Gases are matter with no definite volume or shape. They will take on the volume and shape of whatever they are being contained in. There are three gas laws. The first is Boyle's Law. Boyle's law states that at a maintained temperature, and number of molecules, the volume and pressure of a gas are inversely proportional to each other. Which simply means that the higher the pressure is on a gas, the lower the volume of the gas will be, and vice-versa. The formula for this law is: P¹V¹=P²V². V¹ is the old volume, and P¹ is the old pressure. V² is the new volume and P² is the old pressure. The second gas law is Charles Law. Charles Law states that there is a direct relationship between volume & temperature(K). As Volume increases, so does Temperature, by the same ratio. The third gas law is the Combined Law. The combined law deals with any combination of Pressure, Volume and temperature. The combined law states that Pressure and Temperature are directly proportioned. P¹V¹ Over T¹ = P²V² Over T². The Kinetic Theory of Gases states that: 1) A gas is composed of particles

    Charles’s Law (also known as the law of volumes) is an experimental gas law which describes how gases tend to expand when heated. At constant pressure, the volume of a given mass of an ideal gas increases or decreases by the same factor as its temperature on the absolute temperature scale. It can be written as V∞T where V is the volume or the gas and T is the absolute temperature.…

    The purpose of the experiment was to determine the gas law that can be used to calculate the volume of H2 gas at STP and to calculate the volume of a mole of H2 gas at STP. The research hypothesis was if the combined gas law is utilized, then the volume of H2(g) can be determined at STP because it compares the initial pressure, temperature,and volume with the final pressure, temperature, and volume. Also, if the volume at STP was divided by the number of moles of H2(g) used in the experiment then the volume of a mole of H2(g) at STP can be determined. The method included producing hydrogen gas by reacting an active metal, Mg with HCl acid. The results showed that the molar volume can be determined by using the combined gas law and dividing…

    5.1 Plan: Review the behavior of the gas phase vs. the liquid phase. Solution: a) The volume of the liquid remains constant, but the volume of the gas increases to the volume of the larger container. b) The volume of the container holding the gas sample increases when heated, but the volume of the container holding the liquid sample remains essentially constant when heated. c) The volume of the liquid remains essentially constant, but the volume of the gas is reduced. The particles in a gas are further apart than those are in a liquid. a) The greater empty space between gas molecules allows gases to be more compressible than liquids. b) The greater empty space between gas molecules allows gases to flow with less resistance (hindrance) than liquids. c) The large empty space between gas molecules limits their interaction, allowing all mixtures of gases to be solutions. d) The large empty space between gas molecules increases the volume of the gas, therefore decreasing the density. The mercury column in the mercury barometer stays up due to the force exerted by the atmosphere on the mercury in the outer reservoir just balancing the gravitational force on the mercury in the tube. Its height adjusts according to the air pressure on the reservoir. The column of mercury is shorter on a mountaintop as there is less atmosphere to exert a force on the mercury reservoir. On a mountaintop, the air pressure is less, so the height of mercury it balances in the barometer is shorter than at sea level where there is more air pressure. The pressure of mercury is its weight (force) per unit area. The weight, and thus the pressure, of the mercury column is directly proportional to its height. When the mercury level in the arm attached to the flask is higher than the level in the other arm, the pressure in the flask is less than the pressure exerted in the other arm. This is an impossible situation for a closed-end manometer as the flask…

    The ideal gas law arises from several different gas laws. Boyle’s law describes the inverse relationship between pressure and volume, P ∝ 1/V, for a sample of gas at constant temperature. Charles’ law describes the direct relationship between volume and temperature, V ∝ T, for a sample of gas at a constant pressure. The Gay-Lussac law describes the direct relationship between pressure and temperature, P ∝ T, for a sample of gas at constant volume. Together these lead to what’s referred to as the combined gas law, used to relate the properties of a given sample of gas at two different sets of conditions, labeled 1 and 2.…

    When Henry Cavendish discovered hydrogen in 1774 and Joseph Priestley found oxygen in 1776, neither man would expect the effect these elements could have on modern science, namely rockets. But creating a rocket is just combining these two gases in a closed environment, and one spark. This lab exemplifies just that what happens when the gases H2 and O2 are chemically combined with a spark. In this lab, the objective was to see how far a pipette filled H2 and O2 could travel. One half a centimeter of H2O was added to keep the gases inside, and make sure that only these H2 and O2 where included in the pipettes. Different ratios of each of these gasses where tested: ½ O2 and ½ H2; ⅓ H2, ⅔ O2; ⅓ O2, ⅔H2; ¼ H2, ¾ O2; ¼ O2, ¾H2; all O2; and all H2. Each ratio was tested five times to help provide accurate data. Gases differ greatly from their liquid and solid forms, being affected by temperature, volume, and pressure in unique ways when in this state of matter. Four important laws help in the understanding of the behaviors of gases. According to Charles's Law, the temperature of a gas increases; the volume also increases as long as the pressure and moles are kept constant. To allow for an increase in volume of the gas, as well as temperature, molecules spread out moving faster. Boyle's law states that when the volume of a gas decreases, the pressure increases as long as the temperature and the number of moles is kept constant. As the temperature of a gas increases, so does its pressure, as long as the moles and volume are kept constant According to Gay-Lussac's Law. When gas is sealed in a container, and its molecules are heated, they will move faster and try to spread but stay confined by the container. The push against the container in an attempt to spread out increases the pressure of the gas. Avagadro's Law, states that as the number of moles of a gas increase, so does its volume. According to Avagadro’s Law, it can be said that one mole of a one…

    Behavior of Gases

    Introduction: First of all, the Boyle’s law (pressure-volume law) indicates that the volume of a certain amount of gas given held at a constant temperature differentiates inversely with the applied pressure when there are constant temperature and mass. Equations: PV=C. When pressure goes up, volume goes down (derived from the equation above): P1V1 = P2V2 = P3V3. Furthermore, this particular equation dictates that the product of the initial volume and pressure is equal to the product of the volume and pressure after a change under constant temperature. On the other hand, Charles’ law states that the volume of a given amount of gas held at a constant pressure is considered directly proportional to the Kelvin temperature. Equations: V T or V / T = C. Therefore, as the volume rises, the temperature goes up, as well, and vice versa. Same as the Boyle’s law, initial and final volumes, and temperatures under constant pressure can be calculated also. V1 / T1 = V2 / T2 = V3 / T3. Last but not least, the Gay-Lussac’s law emphasizes that the pressure of a given amount of gas held at a constant volume is said to be directly proportional to the Kelvin temperature. Equations: P T. As the pressure rises, the temperature also rises, vice versa. Like the other gas laws mentioned above, this law’s initial, final volumes, and temperatures under constant pressure can also be calculated. Meanwhile, temperature is the measurement of the kinetic energy of particles inside of a certain object. Thus, the object will increase in temperature if particles have a high amount of kinetic energy. Meanwhile, the object will decrease in temperature if the particles have less kinetic energy. Nonetheless, an object with the lowest temperature tends to have particles that are not moving at all. Last but not least, this particular temperature depicts…

    On heating a liquid, some of the particles will gain sufficient energy to allow them to break away and become a gas. A gas expands to fill its container that is, it does not have a definite size nor volume, neither does it have a definite shape. Gases always spread out to occupy all the space available to them. Gases are very easily expanded or compressed. Tgeir particles are randomly arranged with very large spaces and weak forces between them. Of the three(3) states of matter, the particles if a gas move the fastest and have the largest amount of energy.…
