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

BHOPAL GAS TRAGEDY At 11.00 PM on December 2 1984‚ while most of the one million residents of Bhopal slept‚ an operator at the plant noticed a small leak of methyl isocyanate (MIC) gas and increasing pressure inside a storage tank. The vent-gas scrubber‚ a safety device designer to neutralize toxic discharge from the MIC system‚ had been turned off three weeks prior . Apparently a faulty valve had allowed one ton of water for cleaning internal pipes to mix with forty tons of MIC. A 30 ton refrigeration

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

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

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

After the compression‚ the gas pressure was __________ atm. A) 4.00 B) 2.00 C) 1.00 D) 8.00 E) 16.0 2) A balloon originally had a volume of 4.39 L at 44 °C and a pressure of 729 torr. The balloon must be cooled to __________°C to reduce its volume to 3.78 L (at constant pressure). A) 38 B) 0 C) 72.9 D) 273 E) 546 3) If 50

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

you have an idea about what you want but not quite sure if you want a gasoline or a diesel engine. Well‚ gas and diesel engines are very similar yet different in quite a few ways. At first glance‚ someone who doesn’t know much about either of the two engines might ask‚ “What’s the difference?” To the untrained eye they might look exactly alike‚ but don’t judge the engine by its exterior look. Gas engines are mainly used by the individual in personal vehicles whereas diesels are very popular in the
