    Boyle's Law

    • 1088 Words
    • 5 Pages

    Unlike solids and liquids, gases are known to have both variable volume and pressure. The gas laws were formulated in the late 18th century by various scientists to develop a relationship between the volume, pressure, temperature, and the number of moles of a gas.1 This has allowed scientists today to manipulate these variables in controlled lab settings, to utilize these laws in new innovations such as ventilation systems, and to explain observed biological phenomenon like breathing. Boyle’s Law, the first of these gas laws, was published in 1662, and developed an inverse relationship between pressure and volume, provided that the temperature and the number of moles of gas remained constant.1 It is illustrated by the equation PV = k1, where…

    Gases, solids, and liquids are the three states that a substance can exist as. A gas does not maintain shape and volume. Gases expand to fit and fill the container. While a liquid maintains volume, but not shape and fits the shape of the container it is placed in. Solids can maintain both volume and shape. When a gas exerts force on the walls of a container, this is known as its pressure. Pressure varies based on temperature and volume. Many gas laws were used within this experiment, such as…

    Boyle's Law Lab Report

    • 957 Words
    • 4 Pages

    Purpose The purpose of this experiment is to confirm the functional relationship of Boyle’s law through the use of a manometer. The two parts of this experiment will determine the number of moles of oxygen and the second part will determine the number of moles of nitrogen, that will lead to determine the value of R by measuring P, V, and T. Theory/Principles A physical law such as Boyle’s law states that P, the exerted fixed mass of gas at a constant temperature and V, the volume have a…

    Abstract This lab report focuses on the two experiments on pressure systems conducted, the Marcet boiler and Boyle’s law. The aim of this lab is to investigate in pressure-temperature relationship, Boyle’s law, as well as steam quality. The results of this experiment support both relationship, as well as successfully providing a value for steam quality. For the Marcet boiler experiment, it was found that the higher the system pressure, the higher the saturated temperature. For the Boyle’s law…

    "Law is not law, if it violates the principles of eternal justice." - Lydia Child. The rule of law attests to the idea that the people are to be protected by these very principles. Unfortunately, throughout the world there've been earmarks of injustice from police brutality in the US to the marginalization of women in Afghanistan. Hence, the very reason I want to become a lawyer - to end these perversions. I feel that taking my legal education to the UK will add a dimension to my learning…

    In comparison to Australian Constitution’s implied rights, the US Bill of Rights entrenches the civil liberties of its citizens with the force of law. Amongst the intitial ten rights is the freedom of religion, speech and a fair jury. One point of contestability is political participation - people may not be asked to vote on a referendum for rights in the Bill of Rights to be changed, which in itself, impedes on the right to vote (Amendment 14 and 19). Despite this, the US Constitution is a…

    Further, Boersig (2012, p.244) states children in a police interview are substantially disadvantaged, due to their lack of maturity and inability to necessarily understand the process which they are undergoing, which has the potential to cause them to make false admissions or to breach their own rights, such as the right to silence or to prevent self-incrimination. This potentially leads to a power imbalance between them and any law enforcement officer that may be involved (Boersig 2012,…
