Chap 8

• What is the formula of pressure?

  Pressure= force/area
• What is pressure?

  Amount of force exerted per area
• Example of Pressure

  For example, air that fills a balloon exerts pressure on the sides of the balloon to keep it inflated. Meanwhile, pressure from the atmosphere pushes on the outside of the balloon. As long as the pressure from the inside is greater, the balloon stays inflated. Pressure is proportional to both the force of the push and the area on which it pushes.
• More force means more pressure, and more area means less pressure

  True
• Units of Pressure

  Pascal (Pa) or Atmosphere (atm)
• If the force exerted remains the same, pressure increases as area

  Decreases
• The deeper you go in the ocean, the BLANK the pressure gets

  Higher
• Pressure is BLANK proportional to force

  Directly
• Pressure is BLANK proportional to area, at a constant force.

  Inversely
