Boyle's law

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…

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…

Pressure vs. Volume and Boyle’s Law Pre-Lab Questions According to our modern understanding of the gas laws, there are four measurable properties (variables) of a gas. These variables are P (pressure), V (volume), T (temperature), and n (number of moles). In Boyle’s experiment, which two variables were held constant? Both the temperature (T) and the number of moles of gas (n) were held constant in Boyle’s experiment. Fill in the blanks to summarize the relationship among the gas properties in…

"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…

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,…

To become a criminal lawyer there are certain criteria’s that must be met, like the education requirements, skills and personality traits associated with the position. One must complete an undergraduate degree from a 4-year university or college. Potential criminal lawyers may benefit from courses such as government, history, economics, public speaking and sociology, but these aren’t required to see how most 4-year institutions offer a pre law major. It is also very important that individuals…

they were told. The 1960s is when a union of women were formed and decided to take action to have equal rights not only for whites and blacks but for women as well. Shirley Chisholm was one of these women. In her “Equal Rights for Women” speech, she decided to speak out about acquiring equality for women by establishing an affirmative case for the Equal Rights Amendment. Shirley Chisholm delivered her speech on May 21, 1969 in Washington, D.C., to push for the equal rights amendment in essence…

Legalization of Marijuana AKA WEED! Why we should have to legalization of marijuana is a big topic for a lot of people. Marijuana should be legalized because it’s not that bad as people take it. People see weed as bad drug, when really it’s not. It actually has more positive than it does negative. My opinion for this topic is, we should be able to vote and then decide if it should be illegal, not by one person banding it from the law. Like a president, we understand he is supposed to make the…
