proportional to pressure. This means that as volume increases pressure decreases and vice versa. During inhalation the intercostal muscles and diaphragm contract resulting in an increase in the volume of the lungs and hence the thoracic cavity. As the volume increases, pressure decreases creating an area of sub atmospheric pressure within the lungs. Due to the pressure gradient created, air is able to rush into the lungs from higher pressure outside the body to the lower pressure inside the lungs

America has a problem with the Interstate Highway System. This are ways we can improve and make the roads better. By avoiding Rush Hour and Narrow roads and also urgent situations. We can stop this and improve by taking different routes and building new streets that’s not narrow. We need to start by slowing your speed down, paying attention to the road and driving very safely so others won’t get hurt by the choices others are making. Here are some examples of how Rush Hour can be caused by unsafe

Submission – 225 Magazine LA Roads Article Road conditions in Baton Rouge will get a driver’s attention instantly. Crumbling and congested roads cost the average Louisiana driver thousands of dollars per year in vehicle maintenance and repairs. Windshields are broken, tires get busted, and front ends are knocked out of alignment when driving on Louisiana’s bad roads. Accidents involving serious injuries and fatalities are linked to poor road maintenance; with Louisiana’s current budget crisis, there

Did you know on average at least 30 minutes of travel time is added to and from destinations during peak hours in Brisbane? What is the cause of this? The answer: traffic congestion. Good afternoon Lord Mayor Graham Quirk and representatives of the Department of Transport and Main Roads. Thank you for allowing me the opportunity to speak to you on an issue that affects us all in this great city of ours. Highways are designed to make commuting quicker, however, in peak hour traffic, they resemble

Resistance training is a type of training that requires an athlete to work against a resistance, usually with the use of weights (Fleck and Kraemer,1951). Resistance training can lead to several adaptations over time such as: increased strength, power, mass and endurance (Haff and Triplett 1994). However, before these structural adaptations occur, the body must first go through neural adaptations. Seynnes, de Boer and Narici (2007) stated that it is widely accepted that the initial strength gain

Bad road conditions in Kentucky are a persistent issue that affects the safety and wellbeing of all travelers and Kentuckians alike. From potholes and uneven pavement to inadequate signage and poor lighting, Kentucky's roads are in desperate need of repair and refurbishment. However, this statewide issue is not new. Over the years, heavy traffic, weather, and the old age of the roads themselves has contributed to the worsening of the road conditions. Moreover, Kentucky experiences all four seasons

By the mid-1920s, the main roads near and between large cities were getting seriously congested because of the increase in the number of automobiles. The large volume of traffic created a demand for more lanes and more interstate highways; consequently, the collection of tolls to finance federal highways between the principal cities was considered by the Bureau of Public Roads (BPR) but was rejected. Early in 1937, President Franklin D. Roosevelt directed that a study be conducted that would assess

In the story, “The Outcasts of Poker Flat” by Bret Harte, four of the town’s ‘undesirables’ are banished from Poker Flat so they set off to go to Sandy Bar. On the way there, they meet two newly weds who help them by letting them take shelter in a cabin. However, they wake up to find that one of them in the group, Uncle Billy, has taken the horses and went out on his own so now the rest of them are stuck in the cabin after a snow storm. John Oakhurst takes the role of the leader in the group and

that are emphasized, because they have a deeper meaning. They are emphasized to make sure the reader, as well as the characters in the novel have a truer understanding of what they mean and the importance they bear. Liesel uses two simple words to express how she feels about Ilsa’s situation, but those two words mean more that what she portrays them as, “Two Giant

Comfort. What does this word mean to you? An even better question is where does this mean to you? Everyone strives for a sense of comfort, whether that means what job you are at, who you are around, or what you are doing at the time. The game of baseball includes millions of people striving to find comfort in what they do between the lines, and that is demonstrated by the rituals and superstitions that surround the game of baseball. Certain people need to take the exact same way to the ball field

measuring the temperature, pressure, mass, and volume in a gaseous state. The equation used to determine the molar mass is derived from the Ideal Gas Law equation. The objective of this experiment aims to determine the molecular mass of a

athletes taking part in the risk culture are lifestyle choices. Athletes taking part in sport specific risk behaviours for victory is becoming a social health problem. The risks taken to search for the normalized image are because of social and self pressures as well as the use of performance enhancing drugs. We see in everyday life that athletes are pushing themselves to strive for victory, and a reason for this is because they feel pressured from society. People are continuing to search for the ideal

Volume and Temperature of a Gas By: Jasmine Camacho In this experiment I used both the Boyle’s and the Charles gas laws. Boyle's law states “the volume of a given quantity of a gas varies inversely as the pressure, the temperature remaining constant”. The formula used to help complete this process is PV=constant. Charles law help explain the relationship between temperature and gas volume. And the formula for this is V/T=constant. For this experiment I used the ideal gas law; pV=nRT.

states that the number of moles are proportional to the volume of a gas at a constant temperature and pressure. V = kn where k is the constant of proportionality. Avogadro introduces the idea of particles and how they combine and react in a chemical reaction. A soft drink is an example of Avogadro’s law. When the soft drink is shaken molecules will be released into the air. Therefore the pressure in the bottle is proportional to the number of moles of molecules in the bottle. Boyle’s Law published

Determining the Molar Volume of a Gas Lab Report The purpose of the experiment is to determine the molar volume of hydrogen gas at standard pressure and temperature. Excess hydrochloric acid was placed in a eudiometer and decanted with deionized water. A piece of magnesium ribbon was trapped in a copper wire cage in the eudiometer in order to keep it in place as the more dense hydrochloric acid diffused downward in the inverted eudiometer. The eudiometer was placed in a water bath and the magnesium

“P1V1 = P2V2” shows that as the volume increases, the pressure of the gas decreases in proportion, as long as the temperature stays the same. The relationship between pressure and volume was first noticed by mathematician and astronomer Richard Towneley and experimenter Henry Power. Robert Boyle, a chemist and physicist, confirmed the discovery and published the results in 1662. According to science historians, Boyle’s assistant, Robert Hooke, built the experimental rig. The law is based on air

Kaydyn Dillbeck IDLA Physical Science 10/26/14 Questions for U4A1 Section 1: 1. Kinetic molecular theory- used to explain the behavior of gases and is based upon the following postulates: • Gases are composed of a many particles that behave like hard spherical objects in a state of constant, random motion. • These particles move in a straight line until they collide with another particle or the walls of the container. • These particles are much smaller than the distance between particles,

The goal of this experiment was to use gas-forming reactions to find the best ratio of oxygen to hydrogen for a combustion reaction in order to launch the pipet rocket the farthest. The original hypothesis was that a 2:1 oxygen to hydrogen ratio would result in the farthest launch of the rockets when oxygen added first to the reaction. This hypothesis has been disproven; it has been found through trials that a 1:2 oxygen to hydrogen ratio with the addition of oxygen to the reaction first yields the
