  • This chemistry video tutorial provides a basic introduction to pressure. Pressure is defined as force per unit area. 1 Pascal equals 1 Newton of Force per square meter of area. This tutorial gives you an example of calculating the pressure exerted by a book on the table using the weight force of the book and its cross sectional area. This lecture also discusses the inverse relationship between elevation and atmospheric pressure. As the elevation increases, the atmospheric pressure decreases and the boiling point of water decreases. It's easier to boil water on a mountain since the air pressure is so low but it's harder to boil in a valley that is below sea level. This video also considers the gases that make up the atmosphere. Heavy gases tend to sink down and lighter gases rise. In addition, hot air rises and cold air descends.

    I love the example of a pen tip having more pressure than a finger tip because of the area difference.

    Professor Organic Chemistry Tutor, thank you for an excellent Introduction to Pressure, Force, Area, Atmospheric Gases, Elevation and Boiling Point in AP/General Chemistry. Learning these concepts is a good way to understand nature on planet earth. Nature is undefeated on planet earth. This is an error free video/lecture on TH-cam TV with the Organic Chemistry Tutor.

    At 1:30 the arrow for pressure should point up. When area decreases, the pressure increases. They are inversely related so should point in opposite directions. Either way he explained it correctly.

    I love the course but ozone is a heavier gas than oxygen, why does it then stay up instead of sinking down

    1000Gigapascle pressure required how much surface area ??
    How much bigger an aneroid barometer cell cylinder made with this much of surface area ??
    What type of material are appropriate for this work
    ???

    Dear sir, I have a question-
    How can I achieved the pressure that is 10 N/cm square onto a PVC electrical tape by setting a cylindrical tube which is made from material not causing corrosion and also tube will be filled with the appropriate amount of lead shot, to assure the desired pressure.
    Please tell me the dimensions of the cylinder and the weight of the lead shot.

    Just wanna ask, is (Pa×m² = N) ?

      Force = Area×Pressure (F = A×P)

    Btw i cant understand isnt force= mass × acceleration .......weight = mass × gravitional force

    • @pew7217
      @pew7217 3 ปีที่แล้ว

      Weight is force acting on a body due to gravity and its measured in (newtons).

    • @kellanfeng
      @kellanfeng 2 ปีที่แล้ว

      That's the gravitational acceleration of Earth

    • @kellanfeng
      @kellanfeng 2 ปีที่แล้ว

      9.81 if you want to be specific

  • @bihoyebog1413

    • @arniie5288
      @arniie5288 3 ปีที่แล้ว +1

      Thats the gravitational constant on earth

    • @juanabenjamin856
      @juanabenjamin856 2 ปีที่แล้ว

      It's constant of gravity which is either (9.8 or 10)
