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

Kinetic theory of gases Question: How does odor travel from one place to another? Kinetic theory of gases A gas is composed of atoms or molecules The gas particles are in constant random motion Kinetic energy is transferred between particles as they collide Pressure The force exerted per unit of area Formula: pressure/force area Measured by barometer A vacuum is empty space‚ with no particles or pressure. Atmospheric pressure is the collision air particles with objects Units of

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.
