  • Faster Than Sound - … against this larger amount of air pressure. Blowing air between the balls reduces the air pressure below 14.7 psi. The air pressure around and below the balls remains about the same, pushing the balls together. Blowing air across the top of the strip of paper reduces the air pressure below 14.7 psi. The air pressure below the paper …

  • Weather Basics - … (or air) pressure around us. When air is heated, it expands, which lowers the air pressure. The reverse is also true. Differences in air pressure can cause all types of weather. For example, air naturally moves from … of low pressure, and this movement causes wind. Also, different air pressures are associated with different types of weather. Moving air masses and air pressure are …

  • Water Pressure - … : - Summarize how much air pressure is felt at sea level. - Define atmospheres (ATMs) and millibars (mbs). - Calculate water pressure at any given depth … water pressure while exploring the ocean floor. Pressure 1. Air Pressure a) Pressure is a push or force against a surface. b) At sea level, air pressure … body pushing outward nullify the effect of the air pressure pressing down. 2. Water pressure a) As you go deeper in the ocean …

  • Jet Streams and Weather - … directly proportional to temperature differences between air masses, which in turn are proportional to differences in air pressure. Therefore, one would expect that the high-speed winds of jet streams would occur where temperature differences and pressure differences … answer to pressure differences. 3. Does pressure decrease with altitude more rapidly in cold air or warm air? 4. Does this explain why pressure differences …

  • Donning the Spacesuit - … Shuttle, the suit is pressurized. If you recall, we experience pressure on Earth. If there were no pressure, the air in our lungs would … . They typically dress in the orbiter air-lock. This is an airtight chamber in which the pressure can be controlled. It sits … and the percentage of oxygen in the cabin air is increased. The combined lower pressure and higher level of oxygen means the … -contained unit that is complete with its own oxygen supply, air pressure, power supply and water. The astronaut is no longer in …

  • Bernoulli's Principle - … that as air flows around the wing, the plane is pushed up by higher pressure air under the wing, compared to lower pressure over … the Bernoulli equation. Not only can this equation predict the air pressure around an airplane's wing, but it can also be … faster than the air below, due to the wing's shape. Since the velocity of the upper air increases, its pressure must decrease to maintain balance - as described in Bernoulli's equation. This results in greater pressure below …

  • Out of Breath - … to provide the right amount of oxygen and air pressure - similar to the air and pressure provided while flying in an airplane. The body … . (Answer: True. Engineers have designed systems to provide the right air pressure and oxygen amount during space flight and space exploration.) True … help design systems to give astronauts the right amount of air pressure and oxygen to survive in space.) Lesson Summary Assessment Send …
