Horse power vs. volt power (TS)Pollution‚ global warming‚ and the price of fuel pose real problems for an auto industry churning out gas vehicles‚ however‚ electric vehicles offer hope for the future. (PS)Most electric vehicles look and perform just like a gas vehicle.(SS) For example‚ the electric-powered Dodge Circuit EV resembles the gas-powered Dodge Challenger.(SS) Both sport the bold look of a muscle car‚ And both have all the standard features such as power windows and doors‚ gps‚ air conditioning

Interference with gas exchange Asthma is a common chronic inflammatory disease of the airways characterized by variable and recurring symptoms‚ reversible airflow obstruction‚ and bronchospasm. Common symptoms include wheezing‚ coughing‚ chest tightness‚ and shortness of breath. Asthma is thought to be caused by a combination of genetic and environmental factors. Its diagnosis is usually based on the pattern of symptoms‚ response to therapy over time. In severe cases hospitalization can be required

“THE GAS MAN COMETH” The documentary‚ “Gas Land”‚ by Josh Fox‚ is a film about the problems with contaminated groundwater due to excessive and unregulated natural gas extraction across the country. In the film‚ Fox travels all over to talk to many people who have rented out their land to natural gas companies‚ only to get contaminated water and no help from any company or organization with the problems that ensue. Fox uses many techniques in his film to get across his point that America should

Gas Laws Gases exhibit many qualities that are very different from those of liquids or solids. Gases have particles that are farther apart when compared to liquids and solids. The particles in gases move at different speeds in random directions and they are constantly moving. These particles collide with each other and with whatever container or area they are in. Gases are also very easy to compress. They expand to fill their containers and they occupy far more space than the liquids and solids

greenhouse gas effect The greenhouse gas effect is the accumulation of natural and man-made gas in the atmosphere which does not block sunlight but trap heat to keep the temperature on Earth suitable for life. Imagine a greenhouse that is made of glass that supports plants growth. Visible sunlight can go through the glass but the heat in which it contains can’t go back through the glass‚ thus a greenhouse keeps plants warm allowing them to live and grow happily. The same process with gas replacing

Gas leak detection is the process of identifying potentially hazardous gas leaks by means of various sensors. These sensors usually employ an audible alarm to alert people when a dangerous gas has been detected. Common sensors used today include Infrared Point Sensor‚ Ultrasonic gas detectors‚ electrochemical gas detectors‚ and Semiconductor Sensors. More recently‚ infrared imaging sensors have come into use. All of these sensors are used for a wide range of applications‚ and can be found in industrial
