S5E1 Gaseous Diffusion 1.0 ABSTRACT In this experiment‚ our objective is to find out the gas diffusion coefficient‚ D of acetone in the air. This experiment is conducted at a temperature of 50ºC and atmospheric pressure. The method that is applied to conduct this experiment is called the Winkleman method where the level of acetone (Z) is determined every 15 minutes by using a microscope. With the level of acetone being determined‚ a graph of t/L+Lo (min /mm) vs. L-Lo (mm) is plotted and the

Introduction: The goal of this experiment was to measure the amount of gas produced in various reactions. The Ideal Gas Law was needed in order to calculate the mass of reactants and moles of gas produced: ‚ where is the pressure in atm‚ is the volume in Liters‚ is the number of moles‚ is the ideal gas constant [0.082 (Latm)/(Kmol)]‚ and is the temperature in Kelvins. Considering the units on R‚ it was important to convert pressure‚ volume‚ and temperature to atm‚ L‚ and K‚ respectively. In

The worm is Terrestrial- which means it is related to earths or its inhabitants‚ and is not restricted to moist environments as the worms internal lungs keep it moist. As worms are nocturnal they only are active at night Which gives them less chance to

Pakistan and iran gas pipeline • This is considered to be a very controversial project in Pakistan. • Many peoples agree on the statement that this is an energy lifeline for Pakistan.Some peoples believe it is not be suitable due to US and UN dissents and affairs. • The price of project is appreciate and the price of gas is also reasonable • China set to be the man who will build this pipeline from Iran to Pakistan to Energy starved Pakistan. • It will be 1682 Km long pipeline that will transfer

Pulling up on this old beat down gas station. We all knew it was old when the sign was hanging loosely and swinging with the wind. My dad needed to put gas but I could see he was very skeptical. I rolled my window down getting closer to the gas pump‚ when I smell the most unpleasant scent I have ever smelt. I told my dad we would have to pay for the gas on the inside because the machine was so old that dirt and spider webs built up in the card machine reader. The buttons to the pump were all faded

Greenhouse Gas The greenhouse gas effect is the number one blame for global warming. We could not live without the greenhouse effect. The main gases are ozone‚ nitrous oxide‚ carbon dioxide‚ methane‚ and water vapor. These reflected rays‚ called infrared radiation ‚ keeps the atmosphere warm. They are vital in maintaining the balance in our atmosphere. The greenhouse effect is mostly a result of the sunlight’s energy and the clouds that absorb and reflect heat. Without the greenhouse effect

EXPERIMENT 5 GAS DIFFUSION COEFFICIENT OBJECTIVES: Determine the gas diffusion coefficient of acetone using the established Winkelmann’s method KEYWORDS Diffusivity‚ Gas Diffusion Coefficient‚ Winkelmann’s method OVERVIEW The knowledge of physical and chemical properties of certain materials is important because very often process engineering deal with the transformation and distribution of these materials in bulk. One such property is diffusivity. Mass transfer by diffusion takes

friends‚ looking down you see that your gas tank is on E‚ so you tell your friends that your heading to the gas station. You get to the gas station fill up your tank‚ maybe get a couple of snacks then you check out. You are what the gas station workers call customers. Not only are you just any old customer‚ but you belong in a category just like everyone else that comes into the gas station. There are many different types of people in this world‚ and working at a gas station you interact with all of them

The Ideal Gas Law Lab taught me that hydrogen is lighter than air‚ and can be ignited. The materials used for the experiment include 0.05 grams of magnesium‚ 1M H2SO4‚ water‚ a 100mL graduated cylinder‚ and a beaker. The hydrogen can be ignited with a match. First‚ the beaker is filled with water. The acid is then added to the graduated cylinder‚ with about ¾ inch left at the top‚ which is space for water. Afterward‚ the magnesium is added to the graduated cylinder‚ and it is inverted upside down

Chemistry 1061: Principles of Chemistry I Gas Laws Gas Laws: Pressure‚ Volume‚ and Temperature Introduction Pressure‚ volume‚ and temperature are properties of gases that reveal their relationships when any one of them is varied. Changing the temperature of a gas may change its volume or pressure‚ but how? What are the mathematical relationships between these properties? Are there limits to them? Scientists have discovered through the study of properties of gases that there is indeed a theoretical
