Overview The United States experiences a variety of natural disasters throughout the year. Because of hurricanes on the Pacific‚ Atlantic‚ and Gulf of Mexico coasts‚ earthquakes near the San Andreas and other fault lines‚ volcanic eruptions‚ tornadoes in the plains‚ and floods throughout the Midwest‚ the United States suffers approximately $1 billion in losses each week. From 1990-93‚ losses surpassed those during the previous decade‚ mainly due to Hurricane Andrew‚ the Midwest and Northwest floods

Natural Causes of Climate Change The earth’s climate is influenced and changed through natural causes like volcanic eruptions‚ ocean current‚ the earth’s orbital changes and solar variations. Volcanic Eruptions When a volcano erupts it throws out large volumes of sulphur dioxide (SO2)‚ water vapour‚ dust‚ and ash into the atmosphere. Large volumes of gases and ash can influence climatic patterns for years by increasing planetary reflectivity causing atmospheric cooling. Tiny particles called aerosols

4. To test ideal gas law Theory: Mariotte’s law Charles’ law Gay-Lussac’s law Ideal gas law Apparatus: beaker‚ boiling water‚ thermometer‚ pressure-meter‚ oil‚ closed tube. Procedure: 1) Set up all the apparatus 2) Open the rubber cap. Move the closed tube several times to ensure that the oil is spread equally. 3) Pour boiling water into the beaker and put thermometer into beaker. 1.

1. Natural causes of climate change within the model are livestock (cows) producing methane gas. Human-made causes that can be seen are deforestation for crops‚ homes‚ and businesses. Pollution from cars and planes realeases CO2 into the air and the use of electricty to run the homes and businesses creates greenhouse gases. From 1775 till today‚ cars and planes have been created and contribute to green house gas production. The population has increase and more crops and homes have been built. Oil

CHAPTER ONE 1.0 INTRODUCTION Natural rubber is produced by over 2000 plants species and its main constituent is poly (cis-I‚4-isoprene).a highly unsaturated hydrocarbon. Since 1914 there have been efforts to investigate microbial rubber degradation: However‚ only recently have the first proteins involved in this process have been identified and characterized and have the corresponding genes cloned. Analysis of the degradation product of natural rubber and synthetic rubbers isolated from various

Ideal Gas Law Lab 1. Procedure: First‚ we used a balance to weigh the canister of gas‚ and recorded that mass as the original weight. Then‚ we filled a large bucket with water and recorded the temperature. We then filled a small test tube with water at the same temperature and poured that water into a graduated cylinder to measure the original volume of water in the tube. We then poured the water back into the test tube and placed the tube into the bucket with the opening upwards‚ turning the

Gas Law Problems Boyles Law 1. A gas occupies 12.3 litres at a pressure of 40.0 mm Hg. What is the volume when the pressure is increased to 60.0 mm Hg? 2. If a gas at 25.0 °C occupies 3.60 litres at a pressure of 1.00 atm‚ what will be its volume at a pressure of 2.50 atm? 3. To what pressure must a gas be compressed in order to get into a 3.00 cubic foot tank the entire weight of a gas that occupies 400.0 cu. ft. at standard pressure? 4. A gas occupies 1.56 L at 1.00 atm. What will be the volume

planning to study biology in college‚ the process of natural selection explains so much about the modern day life on earth. There is perhaps no phenomenon more wondrous or perplexing than the development of complex life on our planet. Over the countless years of human existence‚ many have attempted to explain just how life came to be. I too have asked how complex life on earth arose‚ and for this answer‚ I turned to science. The process of natural selection is very important to my worldview because

A disaster is a natural or man-made (or technological) hazard resulting in an event of substantial extent causing significant physical damage or destruction‚ loss of life‚ or drastic change to the environment. A disaster can be ostensively defined as any tragic event stemming from events such as earthquakes‚ floods‚ catastrophic accidents‚ fires‚ orexplosions. It is a phenomenon that can cause damage to life and property and destroy the economic‚ social and cultural life of people. In contemporary
