Pressure In Gases Experiment Hypothesis: Using the recommended tire pressure will provide better gasoline mileage. When the tire pressure is lower than the recommended value‚ the surface contact area between the tire and the road is greater. This will cause greater friction and more energy is required to move the car. As a result‚ more gasoline will be consumed. When the air pressure of a car’s tire is higher than the recommended value‚ the contact area between the tire and the road is reduced.

1)What are all of the greenhouse gases? There are four greenhouse gases that trap and absorb heat on Earth so living organisms can sustain life. Not only are they the greenhouse gases up also make up the 1% in the atmosphere. The greenhouse gases include water vapor (H2O)‚ carbon dioxide (CO2)‚ methane (CH4)‚ and nitrous oxide (N2O). H20 - this is one but it not really talked about on the website 2) Which one is completely human related? (meaning it is not found naturally in the environment)

The greenhouse gases and the resulting greenhouse effect are important. If the greenhouse gases were not present in the atmosphere‚ our Earth would be an icebox. We would have climate similar to that in Mars. The average temperature on Earth would have been about -18 degrees Celsius‚ which is below the freezing point of water. If this was the Earth’s temperature‚ there would hardly be any liquid water on Earth and life as known today would not be possible. Therefore the greenhouse effect is important

overfilling of the sample cylinder but further exacerbated by an increase in temperature between the filling source and the ambient laboratory temperature. A root cause was that the inspector had limited training and experience in sampling liquefied gases. POINTS WORTH REMEMBERING: ➢ Bursting discs will rupture if the ullage space in the cylinder is less than 5%. ➢ Sampling cylinders must be fitted with an ullage tube that is designed to reduce the possibility of overfilling and normally

Report Submitted: June 21‚ 2013 Title: Properties of Gases Purpose: To analyze a few physical and chemical properties of gases as well as using those properties to identify the gases. Procedure: * For Hydrogen I placed a piece of Zn metal into a test tube with diluted HCl. * To produce oxygen I added Hydrogen peroxide to manganese. * Next‚ I added baking soda to vinegar. This caused a quick and energetic reaction! The gas from the reaction I pumped into some Limewater. * Then

According to Plato the role of a central government is to determine where a person belongs or should be positioned society. This belief seems to stem from the ideals of communism or socialism‚ but Plato’s ideas have many departures from those schools of thought. In Plato’s Republic labor is organized by a government run education system that identifies the best roles for each citizen. He compliments his theory of government rule with his theory of justice. Plato argues that justice occurs only
