Kinetic theory of gases Question: How does odor travel from one place to another? Kinetic theory of gases A gas is composed of atoms or molecules The gas particles are in constant random motion Kinetic energy is transferred between particles as they collide Pressure The force exerted per unit of area Formula: pressure/force area Measured by barometer A vacuum is empty space‚ with no particles or pressure. Atmospheric pressure is the collision air particles with objects Units of

Arizona Gas Pipeline On July 30‚ 2003 an Arizona gas pipeline owned and operated by the Houston‚ Texas based company‚ Kinder Morgan Energy Partners‚ burst in Tucson and was shut down. A small portion of the 11-mile pipeline‚ which is about five feet underground burst and at least 10‚000 gallons of gasoline spilled; the pipeline rupture spewed gasoline 50 feet into the air. The Arizona gas pipeline cuts through Tucson’s South and West sides en route from El Paso‚ Texas to Phoenix‚ Arizona and

if they were torn apart. This is notable in the way the soldiers ‘cursed through sludge’‚ and how the ‘men marched asleep’. Despite their fatigue‚ the group of men still have a strong bond‚ as they did not think only of themselves while shouting ‘gas! GAS! Quick‚ boys!’. This explains they are prepared to share their senses‚ and not keep them to themselves only. The bond between the soldiers is also notable when they all watch their mate slowly die‚ while they can do nothing about it. The way the

Fluid mechanics is the branch of physics that studies fluids (liquids‚ gases‚ and plasmas) and the forces on them. Fluid mechanics can be divided into 1) fluid statics‚ the study of fluids at rest; 2) fluid kinematics‚ the study of fluids in motion; 3) fluid dynamics‚ the study of the effect of forces on fluid motion. Fluid Mechanics Overview Fluid is a substance that is capable of flowing. It has no definite shape of its own. It assumes the shape of its container. Liquids and gases are

Experiment 7: Percentage Composition of Kclo3- A Gas law Experiment Anna CunananProfessor Stewart Chemistry 400 T/TH 1:30 PM 18 March‚ 2014 Objectives: In this Experiment‚ we will be decomposing KClO3 into two different compounds‚ KCl and O2. We are given a known mixture that has MnO2 in it to act as a catalyst. When decomposing KClO3 it releases O2 gas‚ which we then collect into the Erlenmeyer flask. The gas then displaces the water into the beaker‚ which we can then calculate the water evolved

details of construction vary among burners‚ each has a gas inlet located in the base‚ a vertical tube or barrel in which the gas is mixed with air‚ and an adjustable opening or ports in the base of the barrel to introduce air into the gas stream. The burner may have an adjustable needle valve to regulate the supply of gas‚ or adjusting the valve on the supply line may regulate the gas supply simply. The burner is always turned off at the gas valve‚ never at the needle valve. Take your burner

"Graham’s Law"‚ which states that the rate of effusion of a gas is inversely proportional to the square root of its molar mass. Graham was also the first to observe that palladium metal is able to absorb large amounts of hydrogen gas‚ especially at lower temperatures. He also observed that when the palladium with hydrogen dissolved in it is exposed to the atmosphere‚ then the metal is likely to become hot and suddenly discharge the gas. Graham found that colloids could be purified by placing them
